Dec 13/14 Geminids Recap

Last night marked the probable peak of the 2014 Geminids. Here in Tucson, we had rain during the day (0.27″) and it was looking iffy as to whether the night would remain clear of clouds and fog. I spent 1h 15m outside between 10:17 and 11:33 pm local time. Though it was very muggy and it sounded like it was still rainy as condensation dripped off the house, the night turned out to be a good one for meteor watching. I was consistently seeing 12-14 Geminids every 15 minutes so just under 1 per minute (with a limiting magnitude of ~6.1).

My camera system had an even better night as it detected 179 meteors of which 139 were Geminids over the course of the night. That is a new record for my meteor camera system having beaten the peak night of the 2010 Geminids by 20 meteors. I will try to get a video from my camera online shortly.

Geminid activity rapidly falls off after the peak. Observers may still be able to see a good number of Geminids tonight though rates will be 1/4 to 1/2 what they were last night.

The International Meteor Organization (IMO) maintains a “live” graph showing the rate of the Geminids as reported by visual observers around the world.
