I watched for 3.75 hours from the Descanso Observatory this morning.
Skies were clear all the way to the coast washing out the western half
of the sky. Looking eastward gave surprisingly good LM's in the mid and
high 6's before twilight commenced. I counted a total of 30 meteors
during the session. Nothing notable occurred and the highlight of the
session was a blue -3 sporadic seen in Delphinus moving toward the
southwest.

The first column is the period watched in Universal Time (PDT+7 hours).
The second column is the percent of the time actually watching the sky.
Time is lost for breaks, plotting, and data entry. The third column is
the average limiting magnitude during this period with a minimum of 4
estimates per period. The last column lists the activity seen during
each period.
I was facing east at an altitude of 75 degrees. No breaks were taken
during this session. ABO = ALPHA BOOTIDS, ETA = ETA AQUARIDS, LYR =
LYRIDS, MVI = MU VIRGINIDS, SAG = SAGITTARIDS (actually in Libra), and
SPO = SPORADIC (random activity)
Beginning Temperature/Relative Humidity: 47 F (8 C) 43%
