Hi, A remarkable nlc last night! Not very bright (~2) but very extensive. Some "tendrils" extending right round to azi 150+. H to 60 deg + Caught some video but not as good as actual visual appearence. Cheers, Bill.
Remarkable it was! I've just asked for a temp update from the radar, although we might have to wait until tomorrow for this morning's data. It does look like (and the time lapse gave the distinct impression of) a flood of cold air to lower latitudes.
Finally got my 2011 NLC season started with a visual short session this morning twixt 02:15 and 02:30 UT. Awakened as nature called I headed downstairs and peeped outdoors to view the sky. Nature had to wait as I viewed an inverted omega of type IVc NLC reaching to 40 degrees altitude with type IIIb at brightness 2. There was an odd separate patch (knot?) with brightness 3. The photo tripod was ready to rumble adjacent to the door but the camera was upstairs so I settled for visual only in the rapidly brightening sky. Large area but not particularly bright. Made me a happy bunny !! ;D
Hi Mark, Did you get a look at it? It was facsinating to see Jupiter rising through it. A little bit denser and it would have been an outstanding photo opportunity. It's been a few years since I've seen the thin tendril like appearence as extensive as this. The pictures I took of it were junk though. Too tired to set the camera properly.... Did you get my message? I was wondering what camera you use? cheers, Bill.
