(meteorobs) Late Observation From California
Back on the morning of May 1, I was out for three hours under great skies
from my Deerhorn Valley location. Once again it was cold and very damp, but
the electric blanket made viewing comfortable. Activity was more impressive
than during my last opportunity on April 9. Although four meteors an hour
sounds a bit slow, the activity was well spaced and kept me alert,
especially during the last hour. The highlight of the session was a
distinctly blue, -1 blue sporadic that appeared in western Aquila.

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. 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 southeast at
an altitude of 60 degrees during the entire session. No breaks were taken.
