(meteorobs) July 16, 2001 Meteor Observations From California



I was able to watch for only an hour and one half this morning. I drove
to the mountains to get above the stratus clouds that are present on
most nights this time of year. The clouds were not thick so there were
significant light domes in the west. I still managed to see 15 meteors.
Contrary to recent reports there were no exceptionally bright meteors
seen. The most impressive meteor was a very slow 1st magnitude Pisces
Austrinid that went upward to my right (west) through Aquila.
Surprisingly there were 3 meteors that appeared to come directly from
the apex, not north or south of it. All 3 of these appeared in
southwestern Pegasus.

The first column gives the period watched stated in Universal Time (UT)
which is PST + 7 hours. The second column gives the percent of that
particular hour actually spent observing the sky. Time was lost for
plotting and data entry tonight. The third column gives the average
limiting magnitude estimated during each period. The last several
columns list the activity seen during each period. I was facing north at
an altitude of 60 degrees during the entire session. No breaks were
taken. ACG = Alpha Cygnids, ANT = (Anthelion Radiant), APX = Apex, CAP =
Alpha Capricornids, NDA = North Delta Aquarids, NPX = Northern Apex, PAU
= Pisces Austrinids, PER = Perseids, SDA = South Delta Aquarids, SPX =
Southern Apex, and SPO = Sporadics (random activity).
