Tonight is the peak of the Geminid meteor shower and its mostly cloudy and overcast. Not just at my place but every location I would have gone for observing. Bummer. From my backyard I observed several Geminids when the sky would clear momentarily.
Interestingly a news report recently posted by NASA says the Geminid shower has been growing in strength for decades. Next years shower will be partially compromised by the 1st quarter moon, perhaps it will be clear.
On a related weather note it was interesting to read the Weather Sealing review for the Canon 7D, with a brief mention of the 5D Mk II. My experience so far, in not so extreme conditions, is that the 5D Mk II holds up very well and with no problems from the cold or moisture.
Update 12.14.2009: early IMO data suggests the shower was very nice this year!
