----------------------------------------------------------
REMARKS:
1. Meteors #3 and #4 appeared at the same time from the radiant.
2. Meteor #1 was a beautiful light green PER fireball with a 
30 degree flight path and left a very distinct train similar to 
a jet contrail.
3. Many of the Perseid meteors were fast and short in flight but
left very distinct/luminous trains.
4. Meteor #21 had a very short flight of only a few degrees directly
out of the radiant.

5. Observed a star like image of nearly constant brightness
(mag. 2.0) a few degrees below the Alpha-Perseus group which 
traveled approx. 10 degrees very slowly to the East and then it
disappeared. Most probably a satelite but fairly bright and 
followed a very smooth/nonerratic path.
