BAA e-bulletin, 2010 Dec. 12
GEMINID METEOR ACTIVITY INCREASING
BAA observers have reported the first meteors of this year's Geminid meteor
shower, which is expected to peak around dawn on Tuesday, December 14.
The maximum is broad, however, and it is important to have a spread of
observers making observations on nights both before and after maximum.
During last year's very favourable display, peak Geminid Zenithal Hourly
Rates approached 140 m/h, and similar rates may be expected this year in the
pre-dawn hours.
The Geminid radiant (at RA 07h 32m Dec +33o, just north of Castor) rises
early on and reaches a respectable altitude well before midnight, but
observers will achieve better results in the early morning hours this year
because the waxing gibbous Moon in Pisces will rather hamper observations
earlier in the night. The early morning hours of December 14, as dawn
approaches, are likely to yield the best observed rates this year, but
watches on the mornings of December 13 and 15 should also be worthwhile,
with the radiant still high in the sky.
Active through to Thursday, December 16, the Geminids are currently the most
active of the regular annual showers, with rates outstripping those of the
Perseids for a 24-hour interval centred on the peak - a real treat for
observers prepared to brave the winter cold and damp.
Additional information about the Geminid shower is given in the 'Notes and
News' section of the December BAA Journal.

details of how to carry out group meteor watches, please visit the BAA
