[amsat-bb] Some shade for Sunsat

["Johann Lochner" <lochner@xxxxxxxxxxxxx>]

Hi folks,

Today is the last day of a five month period for which Sunsat was 
permanently sunlit.  If the last days before this period is anything 
to go by, onboard temperatures will fall by around 10 °C during the 
next week.  Once the battery temperature drops below 20 °C (from the 
current 42 °C) Sunsat will be flipped over, to continue experiments 
with the high resolution imager.  The long term effects of the high 
battery temperature is still uncertain.  Hold your thumbs.  ;-)

PREDICT, by John Magliacane, KD2BD, was used to produce the attached 
table of solar illumination predictions for Sunsat.
