AMSAT News Service Bulletin 117.03 From AMSAT HQ

BID: $ANS-117.03
Stacy Mills, W4SM provides the latest information on AO-40 in this report.
"AO-40 is continuing to drift "downward" in ALON as predicted. This is
making the squint/range combination less favorable for passband use. In
addition, the solar angle is worsening and will shortly exceed 45 degs,
limiting available power and warming the spacecraft considerably as the sun
swings across the omni end of the spacecraft. The AO-40 passbands have been
turned off as of MA=240 (23:50 UTC) on Saturday 4/19. They will remain off
for about 4 weeks (or slightly less) until conditions improve. The beacon
will remain ON during the whole orbit."
M QST AMSAT OSCAR-40 2003 Apr 19
ALON = 35 deg - 18.2 deg/week; ALAT = 20 degs
Orbit 1133 is last passband until ~mid-May. Beacon remains ON.
