Circumstances for this shower – currently the most prolific of the year – should have been ideal in 2004, with New Moon on December 12, and maximum expected around Dec 13d 16h UT, presenting high rates for UK observers on the evening of December 13-14. In the event, weather proved terrible across the UK: observations were limited by hazy skies before peak, and stormy conditions on maximum night, which was best-favoured over North Wales/NW England and, briefly, the Moray Firth.
A total of only 8h 16m observation time (9 sporadics and 176 Geminids) came from the following observers:
N Bone, I Brantigham, P Brierley, M Green, W Leslie, R Sargent (Video), Llandrillo and North Wales Coast AS.
