[amsat-bb:74597] AO-40 Update 2004-01-25

["Stacey E. Mills" <w4sm@xxxxxxxxxxxxx>]

Due to a combination of prolonged extremely heavy transponder use and a 
high solar angle, AO-40's battery voltage dropped momentarily to 24.5 volts 
at MA=132, triggering a "LOW" voltage flag,  and shutting off the 
passbands.   With the passbands off the voltage is coming back up.  The 
torque command has been updated to decrease ALON slightly and improve solar 
angle, which should correct the problem.  The passbands will be back on 
again next orbit.
