My second night of viewing the Orionids had strong Santa Ana winds from the
east. The temperature was an amazing 73F (23C) during the entire session.
The skies were fantastic at the start of the session but deteriorated as the
moon gained altitude. My perception took a dive during the last hour so I
only gave that period a Teff of .5
The highlight of the night was the only Leo Minorid seen. It was an
orange -2 that shot overhead and into the southwestern sky. Very impressive!
Orionid rates were down overall, but the third hour still produced 20. No
Epsilon Geminids were noticed tonight.
Video data from this session will be posted ASAP.
