Geminids Peak

The Geminids meteor shower was forecast to reach its peak last night (Dec. 13/14, Thu/Fri night). According to reports submitted to the International Meteor Organization, Zenithal Hourly Rates (ZHR) may have reached as high as 140-150 per hour around midnight last night Tucson time. This high peak seems to have been rather sharp and other observers recorded ZHRs in the 60-100 range.

Here in Tucson we had a different kind of shower as it rained for the first time in a month. With ~0.58″ of rain last night it was the wettest event since late August. Luckily it does appear that Geminid rates on Wed/Thu night were almost, if not, as good as rates during the peak night. The Geminid rates routinely fall off rapidly after the peak so though some Geminids should be visible tonight rates may be much lower than the past two nights.
