Hi fellow meteor observers,
Last year ; I was already able to observe the whole
declining peak between the Perseid max night and 18
august. Again this year, we are very lucky with the wetter
witch gave me the opportunity to
observe almost the whole rising branch from this splendid meteor
shower.
Please enjoy my other august observations witch gives a nice
view on the slow rise of Perseid activity towards the peak.
With kind regards,
Michel Vandeputte

Remarks
- Short observation session in the dark Belgian Ardennes. Lm 6.8 in Pegasus
(even 6.9-7.0 in the zenith). But during this night a weak convergention line
produced some thunderstorms above Belgium. Many clouds (Ac and Sc). Only between
00.00 - 00.55 I was able to hold a meteor watch. Besides ; I came back to this
place for the Perseid maximum.
-Perseids were quiet active. Highlight ; a - 3 Perseid at 00.48 UT.
