(meteorobs) Sept. Pre-Moonlight Observations
I have taken advantage of a clear first week of September and have
seen the haze of august lift for the most part. I would have liked to
have been able to observe the peak of the aurigid activity earlier last
week, but due to work constraints, had to settle for the earlier part of
the night...at least the moon wasn't out. I spotted a possible late NIA
on the 4/5th, and could not help but notice the general increase in
sporadic activity which was consistant over all four nights of
observations. This may be partly due to the better overall LM's I had
this past week.

Meteor 23 was antehelion (SPI?).
The sky was very clear except for a constant supply
of very small clouds that would pass by one behind the
other, never obscuring the FOV more than 1 or 2%... I hope
f was calculated correctly.
