Season 2010 - 2011 sketching summary
      #4566805 - 05/07/11 07:11 AM

Just like last year, I tried my best to keep a record of pretty much everything going on this year. Here are some of the statistics:

Sky conditions:

Out of 210 days 52 (24%) were clear
Session interrupted by clouds: 8 (15%)
Session plagued by the moon: 12 (23%)
Worst NE lim.mag recorded 4.6 (SQM-L 17.10)
Best NE lim.mag recorded 7.6 (SQM-L 21.45)

Objects sketched:

Messier objects: 24 (16%)
NGC objects: 65 (43%)
IC objects: 9 (6%)
Other objects: 51 (34%)
Total: 149

Objects observed:

New objects observed: 19
Faintest object observed: UGC 731 (14.8 (p) mag)
The most annoying object observed: UGC 10822 / Sh2-188
The most disappointing object observed: low altitude M99
The most impressive object observed: Messier 106

Observing conditions:

Lowest temperature recorded: -28.5C (-19F)
Highest temperature recorded: +19C (66F)
Lowest humidity recorded: 51%
Highest humidity recorded: 99%

Sketching-wise I made some pretty good coverage in Cygnus (43 sketches), Cassiopeia (15 sketches) and Monoceros-Puppis (~20 sketches) region open clusters this year. I failed to observe at least Maffei I (UGCA 34), Palomar 1 and HFLLZOA C026 (reflection nebula). All and all, quite a typical season I'd say.

Jake,

Only within the last few years would I say I envy you, even though you have no dark summer nights.
From my location in the USA the actual number of clear nights (at least partly clear) have gone from 40% in the 1960's to 1980's down to about 15-20% in the last 3 years.

Frank
