> The 2004 Perseids, 4th analysis
>
> A total of 16536 Perseids is now comprised by
> 1567 individual observing periods as used for
> the analysis given below. A short-lived peak
> of activity was observed at 20h56m UT +-4 min
> on August 11, 2004. The precise moment was
> derived from various samplings of the data
> into averages, so it is not directly visible
> in the activity table below.
>
> The time predicted by Esko Lyytinen was 20h54m,
> and it cannot be excluded that observers´ pre-
> judice has ´helped´ match this forecast. The
> study of meteor timings on video recordings
> may clarify this. Any difference is most likely
> below 10 minutes though.
>
> If we assume a background activity of 80-90 during
> the peak, we can derive the full width at half
> maximum (FWHM) to be about 55 minutes (20h25m -
> 21h20m).
>
> Enhanced Perseid ZHRs were observed during the
> entire nights Aug 11/12 and 12/13. This is also
> in line with Esko´s comment that "because Jupiter
> lowers the ecliptic crossing radii in general
> this year, there may be enhanced general activity
> as well."
