(reported by 6 observers)

The white clouds of a Mare Acidarium (30W,+50) northern part seem to move to 
the east compared with the previous day. By the image of Emil Kraaikamp,
orographic clouds were recorded characteristic. Animation is also
understood very well. The shadow by clouds is somewhat dark in the
left-hand side of clouds. (reported by 6 observers)

Apologies,the images sent out under the title Mars 2009 December 12 were
actually Mars 2009 December 14.

Now corrected here,with corrected CM longitude. Please delete the earlier
version (except for R McKim who never recieved it). I don't know why I thought
the date was the 12th.

I though the appearance of Mars tonight to be sufficiently interesting to
justify processing and sending these out as quickly as possible,despite the
alternative attraction of the Geminid meteor maximum.

The white clouds over the Tharsis volcanoes are very clear,and even seem to
cast shadows - or are the shadows due to the volcanoes themselves? The cloud
over the middle volcano,Pavonis,is weaker in the B but strong in the G.
Additionally in the B image clouds are visible over Olympus and within Alba
Patera,a huge crater to the N. near the terminator. This last was apparent to
me visually (through binoviewers) as well and attracted my attention immediately.

シーイングが悪く、また曇る寸前で薄雲が広がっていました。
折角起きたのだから、撮影して置くか・・・の状態でした。
