(meteorobs) Early PERs from around the lamba AND

Hello Wayne, Bernd,

The first so called Perseid (with a flare of magnitude 0 and a 2 second 
train) I saw appeared near Altair.
If I trace it backwards I come close to both radiants.
The second Perseid appeared in starfield 1 in Draco and was evident from the 
vicinity of lambda And.
Best regards,
Koen

Hello Sergei,

I just entered the data Wayne gave into a shower list for UfoOrbit and 
processed
the data from MBB3 by Martin Breukers (Hengeloo, NL) and KLEMOI (one of my
cameras, 20 km east of Cologne) from the night 04./05. July. And indeed from 
the
11 double station meteors 3 were identified as CANs! The other 8 were SPOs.
Attached is the csv output of UfoOrbit for these 3 CANs.

Clear skies
Bernd
