(meteorobs) August 16, 2002 Meteor Observations from California
I was just too tired to venture out on the 15th so I saved all my energy
for this morning. Conditions were near perfect as fog blocked a great
deal of the city lights providing very dark conditions. Activity was
remarkably steady throughout the entire session. The Perseids provided
more than half of all the activity seen. The minor showers, and even the
sporadics were very quiet tonight. There were no real spectacular
meteors seen tonight. The brightest was a nice, yellow -2 that shot
overhead from the north. It was not a Perseid as it missed the Perseid
radiant by at least 10 degrees from a fairly close distance. The fog
kept getting closer and closer throughout the night. Just as I stopped
counting at 5am the sky became overcast. Great timing!

The first column gives the period watched stated in Universal Time (UT)
which is PDT + 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 east at
an altitude of 60 degrees during the entire session. No breaks were
taken. CAP = Alpha Capricornids, KCG = Kappa Cygnids, NDA = Northern
Delta Aquarids, NIA = North Iota Aquarids, PER = Perseids, SDA =
Southern Delta Aquarids, NPX = Northern Apex, SPX = Southern Apex, and
SPO = Sporadics (random activity).
