               PERSEIDS 2005, visual

The 2005 Perseids exhibited a normal to rather low
maximum activity level. There is no clear peak time,
but this can still be due to the limited amount of
data. For the moment we have to assume that the
maximum of the 2005 Perseids was broad, with best
rates between Aug 12, 1h and Aug 13, 3h UT reaching
a ZHR of about 90.

Solar longitudes refer to equinox J2000.0. ZHRs were
computed with a population index of 2.0 which turned
out to be a good guess from a first evaluation of the
magnitude distributions. No personal perception coef-
ficients and no additional zenith correction apart
from sin(hR) are applied.

We are grateful to all the observers who contributed to
the analysis. The following list is STILL INCOMPLETE
because of ongoing data utilization. An update with the
full data set will be issued in a week or two.
