(meteorobs) Geminids 12/13 Dec Iowa

[Bill Godley]

Hello, Paul.
 
I had similar results.  From 6:08 to 08:08 UT, I had about 45 Geminids.  Need to run back the recorder and then post to IMO.  I really hope tonight is clear.

Geminids 12/13 December (Wed night/Thu morning):

The sky wasn't as clear as I would have liked (jet contrail cirrus), but it was a good show for the night before the peak.  The apparent clumpiness was very evident.  I once saw four Geminids in 6 seconds: 0, +1, -2 and +1. The brightest Geminid was -5 and traveled less than 5 degrees going North.  Only one brief Geminid train from a -4 meteor.  The temperature wasn't bad, but I didn't like the wind.  For a while a Great-horned Owl sat on top of a tall utility pole in my FOV and called occasionally.  I was surprised it stayed up there so long in the wind.  It is nice to be able to do meteor observing without glasses!

Again no apparent Monocerotids.  I seem to see far fewer of these than anybody else does.

I was tired and chilly and there seemed no prospect of sky conditions improving so I went home. I'm hoping for good sky tonight.  The Ames Clear Sky Clock doesn't look too great, but the NOAA local weather forecast says "mostly clear".
