Year = 2008 Month = December Day = 01 Day-of-year = 336 Site = Poker_Flat Sunrise = 19:26 Sunset = 23:51 Moonrise = 23:07 Moonset = None Moon_age = 3 Aurora = Unknown Cloud = Overcast all night Magnetometer = Very quiet ASC = Unknown Digital_ASC = Unknown MSP = Ran all night on all channels SDI = Ran all night, poor data Comments = Cloudy, weak signal, and the SDI's Andor camera was suffering from horizontal charge bleeding that introduces a spurious apparent zonal wind. I had improved this problem to some extent, on this night and the previous one, but not eliminated it. I changed the camera's temperature set point to -90C. MC
