        Hi All,

    Visual observations of AO40 could be helpful if there is no recovery in next
hours. The sat. was supposed to spin at around 9 R.P.M before maneuvers. Details on
www.amsat.org. Please, try to look at photometric behaviour, and in the worst case,
presence of debris :-( .

    Last AMSAT bulletin follows.

    Cheers.

AO-40 TELEMETRY TRANSMISSIONS STOP
DEVELOPMENT TEAM INVESTIGATING

Early Wednesday, December 13th, telemetry transmissions from AO-40
stopped while work on the 400 N propulsion system was in progress. An
investigation by the AO-40 development team has begun. They are now
waiting for certain on-board software events to occur on Saturday
afternoon, December 16th. These are programmed to start a spacecraft
emergency routine called 'command-assist' which attempts to
re-establish communications. This offers the best chance of recovering
evidence of the incident which made the telemetry transmissions stop.
When more information becomes available, we will pass it along.

Signed,
Dr. Karl Meinzer, DJ4ZC  (and)   Robin Haighton, VE3FRH
