Remarks
-Early ZHR calculations gives me a
ZHR of 70-80.
-good observing conditions. No cirrus or clouds.
Good transparency resulting in high LM's. Bright moonlight.
-More weak Perseids during the last intervals
(traditional maximum).
-31 % left a persistent train.
-No fireballs ; but a couple of nice -2 Perseids.
Brighter members than during the 2002 return.
-Highest minute counting ; 3 Perseids.
- I worked in 5 minute intervals ; I will work out
a more detailed report in the nearby future (10 minute resolution intervals).
Also in progress : meteor reports from 1-2 / 2-3 / 3-4 / 4-5 / 5-6 / 6-7 / 8-9 /
9-10 / 11 - 12 august.
