AO-40 Update, 2003-05-11




We are about to begin active magnetorquing to hold ALON relatively steady 
and begin to lower ALAT.   Current ALON/ALAT is approximately 330/25, but 
better determination will be possible once the ALAT drops below about 15 
degs. and the earth enters the camera field of view.

We hope to have the passbands on during the first half of the orbit within 
about 1 week, if all goes well.

The A-blk "message of the day" section now includes height, Lon/Lat of the 
subsatellite point, and ALON/ALAT.  All of these values are generated by 
the IHU-1 software based on its orbital and magnetorquing 
calculations.  ALON/ALAT is also updated from the ground when a new 
magnetorquing command is issued.
