    Jupiter and the Moon observation
    From: Alexandre Eremenko
    Date: 2013 Jan 21, 23:38 -0500

    In the evening the weather cleared.
    
    But the temperature fell sharply.
    At the beginning of observation it was 9F, in the end 8F.
    pressure=30.32.
    Sextant was brought out 1/2 before the observation.
    It is interesting that this affected IC very much.
    At noon I measured IC with the Sun, very carefully, and obtained
    consistent result of -0'4. I did not check my termometer, but I believe it
    was about 40F or 50F, and I was standing inside my room with open
    balcony door.
    
    During the night observation, when checked with stars many times,
    it was between -1'1 and -1'4 with 5 checks with different stars.
    
    So I used IC= -1'2 when reducing.
    It never changed so much on my memory, but also I never observed in
    such cold weather:-) I even had to use glowes and hat, and go inside
    after each shot (leaving the sextant outside, of course).

    P.S. Lafayette, IN airport weather station gave completely wrong
    temperature of 52 F. While my termometer showed 8F, and I felt it with
    my skin and even with my bones:-) And this was confirmed by
    Wunderground.com weather
    service.
    
    Alex.
