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.
