Odlične su slike. Čime si slikao? Imaš li neku uvećanu sliku sa pegama?

Sve je više i više pega a Beogradu i dalje oblačno.

Kakve pege na Suncu!Mada se ja naježim kada se vidi ispod korone:  http://spaceweather.com/

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

Velika "pega" na Suncu.Ako sam dobro shvatio tekst,u nju mogu stati "tri Zemlje". Kratak video: http://spaceweather.com/images2014/07jan14/ar1944_anim.gif?PHPSESSID=js8f4irtl7q698d99hfppt7ns1

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.

Nikako da se završi ciklus na Suncu,i dalje ima pega:
