REMARKS:
A nice wind swept out some of the smoke that had been plaguing the area,
although the horizons were still hazy. Moonrise seemed to have quite an
adverse effect on the watch from about 0805 onward.
Meteor 7 was very short and seen going from the middle of Cepheus to
Delta Cephei.
Meteors 20, 68, and 87 were possibly Aquarids of some sort.
Meteor 23 was seen along ESE horizon and was orange for most of its
duration. The terminal burst flashed blue.
Meteors 54 and 89 appeared nebulous. Meteor 89 aligned with the
Northern Apex radiant.
Meteor 55 had a large yellowish head. It was only about 3 degrees long
and seen near the Perseid radiant.
Meteor 75 appeared very low on the southern horizon, traveling east to
west below Capricornus.
Meteor 92 was about magnitude 1 for most of its short flight, but a burst
in the middle reached magnitude -3.
