To Kineski naučnici odavno tvrde.Nešto se dešava,čitao sam negde (nisam uspeo da pronađem tekst) da oni smatraju da se "malo" i uvećalo,ali niko to nije ni potvrdio ni demantovao.Evo i slike te erupcije.
ne znam i cemu se radi. znam da se pretpostavlja da de priblizavamo maunderovom minimumu koji po pretpostavci vodi u ledeno doba, ali to naravno nije tacno.
edit: ali je radjena neka studija da postoji povezanos aktivnosti sunca i nase magnetosfere sa zemljotresima. nisam se nesto mnogo zabavljao time, ali moguce je
Koliko se sećam optužili su Kineze kako su ,zahvaljujući ekonomskom usponu,podigli nivo ugljen dioksida masovnom kupovinom automobila.Oni su se odbranili tako što su optužili Sunce.Šta li je prava istina ???

ne znam, ali od pocetka industrijske revolucije do danas u klimatksim promenama koje nastupaju zbog globalnog zagrevanja sve fabrike i automobili imaju udeo 1 posto. koji je onda promil sto zadnjih dvadesetak godina kupuju vise automobile?!
Sunce se ne smiruje.Ekstremno ultravioletno zračenje zabeleženo je rano jutros.
jos uvek je jaka aktivnost od pre dva dana. marnetosfera zemlje nije ostila nikakve tirbolencije, sto znaci da jos uvek nije toliko jak solarni vetar, za sada :)
danas jos jaca suncana aktivnost dosla do x class flare
sta to znaci ?:D
Quote from: cenicfilip on September 08, 2011, 03:33:18 pm
sta to znaci ?:D
solar flare su eksplozije na povrsini sunca. moze se videti da se zovu i solarne baklje. one oslobadjaju rendgensko zracenje. to zracenje se deli i nekoliko klasa: A, B, C, M, X. od 1 do 10 W/m2 na zemlji. svaka naredna klasa je 10 puta jaca od prethodne. inace klasa x je oko 0,0001 W/m2
je li jasnije :)
pa jeste dosta jasnije.ali dali je stetno po nas? mislim svako zracenje je stetno....samo me interesuje u kojoj meri to jest koja klasa zracenja sunca je opasna po nas?
po nas nista. ali astronauti u svemirskoj stanici bi mozda mogli biti ozraceni. rendgensko zracenje utice na jonizaciju u gornjim delovima atmosfere pa onda vidimo polarnu svetlsot.

Neverovatno. Jadna kometa. Ocekivao sam da ce se pojaviti sa druge strane kad ono.. nesto jos spektakularnije.
Sunce nastavlja da greje!Evo izveštaja sa sajta "SpaceWeather" :
QUIET SUN: How quiet can a star with eight sunspot groups be? Pretty quiet, it turns out. The sun has that many sunspots and more facing Earth, yet none of them is producing flares. Regard this plot of the sun's X-ray output for the past two days; it has almost flat-lined:
Perhaps this is the calm before the storm. Sunspot AR1319 has a 'beta-gamma' magnetic field that harbors energy for strong M-class flares. NOAA forecasters estimate a 30% chance of such an eruption in the next 24 hours. Solar Flare alerts: text, voice.
Juče je bila snažna erupcija na Suncu.Sva sreća udariće u Mars 8)

Najverovatnije 15 ili 16 decembra još jedna kometa će pasti na Sunce.Nadam se da će biti spektakularno:
They came from outer space--and you can have one! Genuine meteorites are now on sale in the Space Weather Store.
GEMINID METEOR SHOWER: The Geminid meteor shower peaks on Dec. 13th and 14th. Bright moonlight will interfere with the display, but not obliterate it. Forecasters expect observers with clear skies to see as many as 40 meteors per hour. The best time to look, no matter where you live, is between 10 pm local time on Tuesday, Dec. 13, and sunrise on Wednesday, Dec. 14th.

SIGNIFICANT COMET PLUNGES TOWARD THE SUN: A comet nearly as wide as two football fields (200m) is plunging toward the sun where it will most likely be destroyed in a spectacular light show on Dec. 15/16. Although Comet Lovejoy (C/2011 W3) could become as bright as Jupiter or Venus when it "flames out," the glare of the sun will hide the event from human eyes. Solar observatories in space, however, will have a grand view. Yesterday the brightening comet entered the field of view of NASA's STEREO-B spacecraft:
"You can clearly see the comet heading diagonally through the images," says Karl Battams of the Naval Research Lab who prepared the animation. "During the 16-hour sequence, the comet brightens from magnitude +8 to +6.5, approximately."
It will soon grow much brighter. "This comet is a true sungrazer, and will skim approximately 140,000 km (1.2 solar radii) above the solar surface on Dec. 15/16," notes Battams. At such close range, solar heating will almost certainly destroy the icy interloper,creating a cloud of vapor and comet dust that will reflect lots of sunlight. The Solar and Heliospheric Observatory (SOHO) will have a particularly good view.
Discovered on Dec. 2nd by amateur astronomer Terry Lovejoy of Australia, the comet is an unusually large member of the Kreutz family. Kreutz sungrazers are fragments of a single giant comet (probably the Great Comet of 1106) that broke apart back in the 12th century. SOHO sees one plunging into the sun every few days, but most are small, no more than 10 meters wide. Comet Lovejoy is at least ten times larger than usual.

Misterije ne prestaju sa kometom Lovejoy:citat na sajtu Spaceweather-
SPIRAL COMET TAIL: As Comet Lovejoy recedes intact from its Dec. 16th close encounter with the sun, researchers are pondering a mystery: What made the comet's tail wiggle so wildly in transit through the sun's atmosphere? The effect is clear in this sequence of extreme UV images recorded by NASA's STEREO-B spacecraft:
"Why the wiggles?" wonders Karl Battams of the Naval Research Lab. "We're not sure. There might be some kind of helical motion going on. Perhaps we're seeing material in the tail magnetically 'clinging' to coronal loops and moving with them. [Coronal loops are huge loops of magnetism that emerge from the sun's surface and thread the sun's atmosphere.] There are other possibilities too, and we will certainly investigate those!"
Battams notes that these images can be combined with similar images from STEREO-A on the other side of the sun to produce a three dimensional picture. "When we pair these together, and throw in the SDO images too, we should be able to get an incredibly unique 3-D picture of how this comet is reacting the the intense coronal heat and magnetic loops. We are going to learn a lot."
Da se podsetimo o temperaturama na i u blizini Sunca: citat sa wikipedie-
Hromosfera Za više informacija pogledajte članak hromosfera
Hromosfera je niži sloj sunčeve atmosfere, proteže se iznad fotosfere do visine oko 10 000 km. Znatno je ređa od fotosfere i nepravilnog oblika. Sa Zemlje se primećuje samo za vreme potpunog pomračenja Sunca. Porastom visine gustina atmosfere opada, ali se povećava temperatura. Ove promene gustine i temperature izražene su u prelaznom području između hromosfere i korone.
U hromosferi se događaju izboji gasa stvarajući efekte koje nazivamo prominencije i sunčeve baklje.
Prominencije (protuberance) su oblaci ili mlazovi usijanog gasa izbačenog uvis. Mogu se uzdići do visine 150 000 km iznad fotosfere, kroz hromosferu i koronu. Gušće su od okolne tvari i dostižu temperaturu oko 20 000 K. Na sličan način dolazi do pojave baklji, mlazova gasa koji se brzo podižu unutar hromosfere i padaju nazad. Vreme trajanja jedne sunčeve baklje je oko 10 min.
[uredi] Korona Za više informacija pogledajte članak korona
U višim slojevima sunčeve atmosfere, koroni, temperatura nastavlja da raste do 1 000 000 K. Nije sasvim jasno zbog čega se događa ovaj porast temperature. Pretpostavka je da ga stvaraju strujanja gasa pod uticajem magnetnog polja.
Spoljašnji delovi korone stalno gube masu u obliku sunčevog vetra.
Zašto nije isparila ???

Neverovatni prizori na Norveškom nebu :o
Evo i novog talasa 24-25.1.2012 : ALMOST-X FLARE AND CME: This morning, Jan. 23rd around 0359 UT, big sunspot 1402 erupted, producing a long-duration M9-class solar flare. The explosion's M9-ranking puts it on the threshold of being an X-flare, the most powerful kind. NASA's Solar Dynamics Observatory captured the flare's extreme ultraviolet flash.
The Solar and Heliosphere Observatory (SOHO) and the STEREO-Behind spacecraft have both detected a CME rapidly emerging from the blast site. Analysts at the Goddard Space Weather Lab estimate a velocity of 2200 km. There is little doubt that the cloud is heading in the general direction of Earth. A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth's magnetic field on Jan. 24-25 as it sails mostly north of our planet. Stay tuned for updates.Solar flare alerts: text, voice.

Da stvarno interesantno, izgleda da brzina radioaktivnog raspada nije konstantna ???
Ovo moze imati veliki uticaj na metodologiju datiranja putem radioaktivnog raspada koja je danas dominantna u raznim oblastima nauke.
Kako je to uticalo na kosmonaute u svemirskoj stanici?

Ponovo pojačana radijacija sa Sunca: http://spaceweather.com/images2012/29jan12/snow.gif?PHPSESSID=99644jqngbk63ijbr0ql57tgl0
RADIATION STORM: Accelerated by Friday's X-flare, energetic protons from the sun are still swarming around Earth on Jan. 29th. The radiation storm ranks S2 on NOAA scales, which means it is not a severe storm. Nevertheless, it can still affect spacecraft and satellites at the nuisance level. Click on the image for an animated demonstration:
That was a coronagraph image from the Solar and Heliospheric Observatory (SOHO). The many speckles and streaks are energetic protons striking SOHO's onboard digital camera. Stronger radiation storms (S4 to S5) can fill images like these with "snow," rendering them useless for normal operations. The current storm will probably subside later today and restore SOHO's clear view of the sun.

Stiže novi "cunami" sa Sunca:
ANOTHER CME TARGETS EARTH: Sunspot AR1429 has unleashed another strong flare, an M6-class eruption on March 9th at 0358 UT. The blast hurled a coronal mass ejection almost directly toward Earth. According to analysts at the Goddard Space Weather Lab, the CME will arrive on March 11th at 0649 UT (+/- 7 hr). NOAA forecasters say the odds of a strong geomagnetic storm at that time is 50%. Aurora alerts: text, phone.
The same eruption that hurled the CME toward Earth also produced a monsterous tsunami of plasma on the sun. NASA's Solar Dynamics Observatory recorded the shadowy but powerful wave rippling away from the blast site:
The tsumani was about 100,000 km high and raced outward at 250 km/s with a total energy of about 2 million megatons of TNT. Such waves often underlie CMEs like the one en route to Earth now.
Animated forecast tracks show that the CME will also hit the Mars Science Lab (MSL) spacecraft on March 12th followed by Mars itself on March 13th. Mars rover Curiosity onboard MSL might get some interesting readings as the cloud passes by.
Od kako je počelo na televiziji da se javlja o pojačanoj Sunčevoj aktivnosti, to više srećem ljude koji se pronalaze u stvari da je to uzrok njihovoj nervozi, nesanici ili dugom spavanju, gubitku apetita, sitosti, povećanom apetitu, lošim snovima, dobrim snovima, maloj plati, lošem poslu, pogrešnoj politici, prodatom Kosovu, neizbačenom đubretu od prošle nedelje iz dvorišta, velikom snegu, a sada naglom otopljenju, kao i smaku sveta 21.12.2012. godine :o >:( ???
Tek sad mi je jasno zašto skače EVRO ;D

WEEKEND SOLAR FLARE: Sunspot AR1429 erupted again over the weekend. On Saturday, March 10th, it produced a powerful M8-class flare that almost crossed the threshold into X-territory. During the flare, New Mexico amateur astronomer Thomas Ashcraft recorded a series of radio bursts at 21 and 28 MHz:
Dynamic spectrum courtesy Wes Greenman, Alachua County, Florida
The roaring sounds you just heard are caused by shock waves plowing through the sun's atmosphere in the aftermath of the explosion. "There is incredible complexity in the waveforms," notes Ashcraft. "This is a recording of one of the most turbulent events in all of Nature!"

Opet nas "pogađa" Sunčev vetar:
STRONG FLARE, INCOMING CME: Departing sunspot AR1429 unleashed another strong flare on March 13th, an M7-class eruption that peaked around 1741 UT. Although the sunspot is no longer directly facing Earth, the blast will affect our planet. Analysts at the Goddard Space Weather Lab say a CME is en route to Earth, and its impact on March 15th at 06:20 UT (+/- 7 hours) could trigger minor to moderate geomagnetic storms. Also, protons accelerated by the flare are swarming around Earth, causing an S2-class radiation storm. Space weather alerts: text, phone

ANOTHER CME FROM SUNSPOT AR1429: Transiting the farside of the sun, never-say-die sunspot AR1429 erupted during the late hours of March 26th, producing its 11th major CME. The Solar and Heliospheric Observatory (SOHO) photographed the cloud flying over the sun's eastern limb:
According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the CME will hit two spacecraft, STEREO-B and Spitzer, on March 28th. Earth is not in the line of fire.
This event shows that AR1429, the source of several strong geomagnetic storms in early March, is still active. It will begin turning back toward our planet about a week from now. Stay tuned.

Pojačano zračenje sa Sunca: SOLAR ACTIVITY INTENSIFIES: Huge sunspot AR1476 is crackling with M-class solar flares and appears to be on the verge of producing something even stronger. The sunspot's 'beta-gamma-delta' magnetic field harbors energy for X-class flares, the most powerful kind. Earth is entering the line of fire as the sunspot rotates across the face of the sun.
This morning, May 10th around 0418 UT, sunspot 1476 unleashed an impulsive M5-class solar flare. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
Apparently, the almost-X class explosion did not hurl a significant CME toward Earth. NOAA forecasters estimate a 65% chance of more M-class flares and a 10% chance of X-flares during the next 24 hours. X-flare alerts: text, phone.

RADIATION STORM: A radiation storm around Earth is subsiding. The storm began during the early hours of May 17th when a strong M5-class flre accelerated a fusillade of solar protons in our direction. At its peak, the S2-class storm was capable of confusing spacecraft imaging systems and causing 'single event upsets' in orbiting electronics. Radiation storm alerts: text, phone.
The explosion tthat caused the radiation storm also hurled a coronal mass ejection (CME) into space. SOHO recorded the cloud racing away from the sun faster than 1500 km/s:
The speckles in the movie are caused by energetic protons hitting the observatory's detector. This kind of "snow" is a sign that a radiation storm is underway.
This CME is not heading for Earth. It will, however, deliver a glancing blow to Mercury. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the cloud will reach the innermost planet on May 17th at 15:09 UT (+/- 7 hr).

Velika erupcija na Suncu.Nema opasnosti za Zemlju: PHOTOGENIC, NOT GEOEFFECTIVE: A long filament of magnetism snaking over the sun's northwestern limb erupted this morning, hurling much of itself into space. NASA's Solar Dynamics Observatory recorded the blast.
A bright CME billowed away from the blast site. Because of the explosion's location on the NW edge of the solar disk, the cloud will not hit Earth. This event was photogenic but not geoeffective.

Rekordno zračenje sa Sunca: ALMOST X-FLARE: Big sunspot AR1515 erupted on July 2nd at 10:52 UT, producing an M5.6-class solar flare that almost crossed the threshold into X-territory. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
A pulse of x-rays and UV radiation from the flare illuminated Earth's upper atmosphere, producing waves of ionization over Europe. Such waves alter the propagation of low-frequency radio transmissions. In Lofoten, Norway, Rob Stammes recorded the ionospheric disturbance using a 60 kHz receiver: data.
The eruption also hurled a CME into space, but not directly toward Earth. The south-traveling cloud could deliver a glancing blow to our planet's magnetosphere on July 4th or 5th. Stay tuned for updates. [SDO movie]

Solar activity is already high. The addition of this new active region could boost the chance of flares even more. For a better view, check back later today as the sunspot turns more squarely toward Earth

Slobodno vremeVesti.111....Nova erupcija na Suncu, solarna oluja sutra pogađa Zemlju
M. Milikšić | 07. 07. 2012. - 18:17h | Foto: AFP | Komentara: 8
U aktivnom sunčevom regionu 1515 došlo je danas do nove jake erupcije, poslednje u nizu u proteklih nekoliko dana. Očekuje se da će solarna oluja nakon te erupcije doći do Zemlje, jer je sunčeva pega 1515 trenutno okrenuta ka našoj planeti.
Sunčeva aktivnost je na visokom nivou, pa naučnici posmatraju aktivni region 1515. Oni smatraju da su šanse da će taj region u sledećih 24 sata emitovati nove oluje čak 80 odsto.
Iz Centra za predviđanje svemirskog vremena pri NOAA kažu da će 8. jula biti geomagnetne aktivnosti, jer će visoko nabijene čestice nakon dve nedavne erupcije na Suncu, doći do Zemlje. Ove oluje takođe bi mogle da dovedu do ometanja radio talasa i, naravno, da uzrokuju polarnu svetlost.
Američka svemirska agencija NASA javila je da je solarna oluja klase M pogodila Zemlju, uzrokujući kraći prekid radio talas rano ujutro 5. jula.
Astronomi stalno posmatraju aktivni region 1515, kompleks sunčevih pega na površini zvezde okrenut ka Zemlji. Sunčeve pege uzrokuju područja magnetne aktivnosti na površini Sunca koja su sposobna da dovedu do erupcije energije i čestica koji potencijalno mogu da pogode našu planetu.
Astronomi, koji od 3. jula posmatraju region 1515, kažu da je emitovano 12 solarnih oluja srednje jake klase M - najjača je oluja klase X, iza koje se nalazi klasa M.
NASA je objavila da je oluja klase M u četvrtak bila upola jačine najslabije oluje klase X. Ta slaba oluja je, međutim, iako na kratko, dovela do prekida radio talasa.
Američka Nacionalna kancelarija za okeane i atmosferu (NOAA), u Koloradu, klasifikuje ometanja radio talasa na skali od jedan do pet, odnosno od R1 do R5, pa su tako prekidi usled oluje 5. jula dobili slabu oznaku R2.

Nešto mi tu ne štima, vijest je neistinita, a i Discovery ju je povukao.
Grupa pjega pod oznakom AR 1515 je na samom zalasku za zapadni Sunčev rub i ne može svojim aktivnostima uzrokovati više ništa što bi moglo pogoditi Zemlju. No, to se dogodilo ranije (http://www.spaceweather.com/archive.php?view=1&day=04&month=07&year=2012), Bila je vijest i na AM (http://www.astronomija.co.rs/sunev-sistem/sunce/6306-sunce-opet-napada.html), a ja sam se bacio na snimanje te grupe pjega (http://www.astronomija.co.rs/fotografija/6307-sunce-danas.html). Od događaja na Zemlji nije bilo baš ništa jer je oblak visokoenergijskih nabijenih čestica sa Sunca u potpunosti promašio Zemlju.

Jako lepo Danijele! :)
Kolega iz Francuske je napravio odličan snimak grupaciju pega pod oznakom AR 1520 sa sajta "SpaceWeather.com":
One of the biggest sunspots in years, AR1520, is turning toward Earth. Christian Viladrich of Nattages, France, photographed the behemoth on July 7th.
"It looks like an expanse of land on the sun," says Viladrich.
Despite the resemblance to land, however, the vast dark cores of sunspot AR1520 are not solid. They are made of magnetism. Each one is a magnetic island nearly as wide as Earth floating in a sea of solar plasma.
The magnetic field of this enormous sunspot is tangled, and harbors energy for strong solar flares. NOAA forecasters estimate an 80% chance of M-flares and a 25% chance of X-flares during the next 24 hours.
Edukativni film o Suncu i njegovom uticaju na Zemlju: http://www.nasa.gov/mission_pages/sunearth/news/X-class-flares.html
Pojačano X zračenje sa Sunca:
X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th at 1653 UT. Because the sunspot was directly facing Earth at the time of the blast, this is a geoeffective event. Stay tuned for updates about possible CMEs and radio blackouts. Solar flare alerts: text, voice.
NASA's Solar Dynamics Observatory recorded a flash of extreme ultraviolet radiation from the blast site.
The UV and X-ray pulse from the flare will have partially ionized Earth's upper atmosphere on the dayside of our planet, disturbing the normal propagation of radio signals. Watch the Realtime Space Weather Gallery for possible reports of sudden ionospheric disturbances and other effects.
Danas je naša Zemlja zasipana solarnim vetrom

Evo i teksta sa "SpaceWeather" a:
X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th. Because the sunspot is directly facing Earth, everything about the blast was geoeffective. For one thing, it hurled a coronal mass ejection (CME) directly toward our planet. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the CME will hit Earth on July 14th around 10:20 UT (+/- 7 hours) and could spark strong geomagnetic storms. Sky watchers should be alert for auroras this weekend. Geomagnetic storm alerts: text, voice.
The explosion also strobed Earth with a pulse of extreme UV radiation, shown here in a movie recorded by NASA's Solar Dynamics Observatory.
The UV pulse partially ionized Earth's upper atmosphere, disturbing the normal propagation of radio signals around the planet. Monitoring stations in Norway, Ireland and Italy recorded the sudden ionospheric disturbance.
Finally, solar protons accelerated by the blast are swarming around Earth. The radiation storm, in progress, ranks "S1" on NOAA space weather scales, which means it poses no serious threat to satellites or astronauts. This could change if the storm continues to intensify. Stay tuned.

Magnetni most na Suncu: MAGNETIC BRIDGE: Sunspots AR1528 and AR1529 appear to be far apart. More than 200,000 km of stellar surface separate the two. Nevertheless, they are connected by a tubular bridge of magnetism. NASA's Solar Dynamics Observatory (SDO) photographed the vast structure on July 24th.
This extreme ultraviolet image traces the bridge via the glow of hot plasma it contains. Material can flow back and forth inside the tube, allowing one sunspot to respond to what the other is doing.
Researchers once thought that sunspots were independent operators, but SDO has shown over and over again that widely-spaced sunspots can be linked. An eruption in one can set off an explosion in another, leading to a chain reaction that can spread around the circumference of the sun. The global eruption of August 2010 is a memorable example.

Sunce je dostiglo maximum?Možda:
SO THIS IS SOLAR MAXIMUM? Forecasters have long expected the Solar Max of 2013 to be the weakest of the Space Age. It might be even weaker than they thought. As shown in this 20-year plot of sunspot counts vs. time, the sun is underperforming.
Sunspot numbers are notoriously variable, so the actual counts could rapidly rise to meet or exceed the predicted curve. For now, however, the face of the sun is devoid of large sunspots, and there have been no strong flares in more than a week. The threshold of Solar Max looks a lot like Solar Min. NOAA forecasters estimate no more than a 1% chance of X-class solar flares in the next 24 hours.
Na Suncu baš dosta pegica.Da li se zna kada ih je bilo najviše :-\

Odakle ti da je to suprotno očekivanju ???
Naprotiv, to je sve sasvim očekivano kao što uostalom i jasno piše u tekstu sa linka koji si postavio:
QuoteThis intense period of solar activity isn't unexpected; it's all part of the natural solar cycle that ebbs and flows over an approximate 11-year cycle. The peak of this cycle, called "solar maximum," is expected in 2013,...
Podebljano u bukvalnom prevodu znači "nije neočekivano" ::)
Sve u svemu Sunašce naše milo i drago je sve interesantnije i interesanttnije za posmatranje.
Hvala sale11472 :) Broj pega se povećava,slika od danas 4.1.2013 godine.
Sunce dobilo "male boginje" :o Evo snimka od danas 5.1.2013 g. i teksta sa sajta Spaceweather:
INCREASING CHANCE OF FLARES: The sun is peppered with spots: There are now more than a dozen numbered active regions scattered around the solar disk. As the sunspot count increases so does the chance of flares. NOAA forecasters estimate a 25% chance of M-class eruptions and a 5% chance of X-flares during the next 24 hours. Solar flare alerts: text, voice.
To illustrate the growing spottiness of the sun, each active region in this Jan. 5th image from NASA's Solar Dynamics Observatory is circled.
The most active sunspot so far is emerging over the sun's northeastern limb. Crackling witth flares, it unleashed an M1.7-class eruption on Jan. 5th at 09:34 UT that sent a wave of ionization rippling through the upper atmosphere over Europe. More flares appear to be in the offing; stay tuned.
Hm,da li je NASA pogrešila?

VERY SPOTTED SUN: Solar activity is still relatively low, but the appearance of the sun suggests the quiet might not last. Over the weekend, a profusion of new sunspot groups peppered the solar disk with dark cores--each one a potential source of eruptions. NOAA forecasters estimate a 35% chance of M-class flares and a 5% chance of X-flares during the next 24 hours. Solar flare alerts: text, voice.
There are so many spots on the sun, even a jumbo jet cannot hide them.
Raffaello Lena took the picture on January 5 not far from the international airport in Rome, Italy. "An animation of the flyby is available here," he says.

Velika koronalna rupa na Suncu.Tekst sa Spaceweather: CORONAL HOLE: The biggest thing on the sun today is not a sunspot, it's a coronal hole. The yawning dark gap in the sun's atmosphere is almost directly facing Earth, as shown in this June 25th image from NASA's Solar Dynamics Observatory.
Coronal holes are places where the sun's magnetic field opens up and allows solar wind to escape. A stream of solar wind flowing from this particular coronal hole will reach Earth on June 29-30. Because the coronal hole is straddling the sun's equator, the solar wind it is sending our way should make a direct hit on our planet's magnetic field. The impact could spark geomagnetic storms around the poles. High-latitude sky watchers should be alert for auroras at the end of the month

HUGE SUNSPOT TARGETS EARTH: One of the biggest sunspots in years is crossing the center of the solar disk, putting Earth in the way of potential eruptions. Rocky Raybell photographed the active region named "AR1944" yesterday from his backyard in Keller, Washington.
The sprawling sunspot contains dozens of dark cores, the largest big enough to swallow Earth three times over. This makes it an easy target for amateur solar telescopes. Raybell used a backyard 'scope capped with a Baader solar filer to capture both the sunspot and trees in the foreground. Photo details may be found here.
Although AR1944 has been mostly quiet for days, flares are in the offing. The sunspot has an unstable 'beta-gamma-delta' magnetic field that could erupt at any time. NOAA forecasters estimate a 75% chance of M-class flares and a 30% chance of X-flares on Jan. 7th.
Stižu nove pege.Slika i tekst sa "Spaceweather":

OLD SUNSPOT RETURNS, SOLAR ACTIVTITY INCREASES: Crackling with solar flares, a large sunspot is emerging over the sun's southeactive limb. It appears to be AR1944, returning after a two-week trip around the farside of the sun. Earlier today, astronomer Karzaman Ahmad photographed the active region from the Langkawi National Observatory in Malasia.
According to tradition, sunspots that circle around the farside of the sun are re-numbered when they return. The new designation of AR1944 is AR1967. "Sunspot AR1967 is as big as Earth!" notes Ahmad.
Earlier this month, AR1944/AR1967 produced an X1-class solar flare and one of the strongest radiation storms of the current solar cycle. Is round 2 about to begin? Solar activity is definitely increasing as AR1967 comes around he bend. Earth orbiting satellites have detected at least five M-class solar flares since yesterday, including this one recorded on Jan. 28th (07:30 UT) by NASA's Solar Dynamics Observatory.
More flares are in the offing. NOAA forecasters estimate a 5% chance of X-flares and a 50% chance of M-flares during the next 24 hours.
