(meteorobs) 8/11-12/2002 Perseids from Vancouver Washington



Another Perseid report below:
But first another highlight of the night's observing:
At 2:40 am local time I was able to watch the tri-satellites that fly in
formation.  They formed a slightly distorted isosceles triangle with a
few degrees angular seperation.   They moved together in formation  from
overhead to the North-East
If you want to know more about  satellites in formation do a search of
the old Meterobs  posts for  SB-WASS  and/or  NOSS 2-1 (C-E)
(I don't know which satellite group  I saw this morning -  too many
hobbies -  aaaarrrgggh)
