This was a more active day for the monsoon and a string of thunderstorms
hit the mountain for two hours before sunset. Debris clouds were stubborn
and persisted most of the night as the storm activity moved west and away
from the observatory. There were three partial clearings during the night,
with the best and most sustained being in the last hour of the night and
in early morning twilight. In all, over a half dozen blazars were observed
in seeing of about 1.5 arcsec.
