(meteorobs) Dec 11/12 Geminids from the NJAA

[meteoreye at comcast.net]

>From the NJAA Observatory in High Bridge NJ, managed 4.2 hours before my toes ended my session. Forgot to double sock : Temp decreased from 24 to 20 F (~ -5C) but as Richard experienced in Maryland, winds were light. Skies were clear, if not particularly transparent. Highlight was a superb -5 NTA/ANT Fireball ot 0647 UT that fragmented into dozens of pieces as it passed from 55 degrees due south toward the southeast. I was recording LM data at the time, and my instinctive reaction at seeing it made my tape no longer acceptable for family listening. ;) 



F was 1.00 throughout, FOV was due south at 60 degrees elevation. Looked for PUP after the first 1.2 hours when radiant was above horizon, saw none. Looked for COM at both the IMO Working list and video locations, saw none. PSU shower is from Sirkos WGN 37:4 list, as well as NTA position (last day of video indicated activity)
