Remarks
-many weak Perseids ( same display as 2001). A few bright
ones.
-no fireballs were observed.
- some point meteors.
-minute countings : Perseid rates went up to 5 stream members.
Regular 2 or 3 minutes without observing one single Perseid.
- yellow was the most observed colour.
-39.5 % left a persistent train.
-Fog made an end of the observing session at 02.18 UT. What a
pity.Normally we can observe here until 03.00 UT.
A new report of 13-14/8 will follow soon.
Clear skies,
