                           ULYSSES STATUS REPORT
                              February 5, 1991

     The Ulysses spacecraft is not responding to commands transmitted
over the 34 meter antenna in Madrid yesterday.  The station performed
a manual tune last night with 18 kw transmitter output.  The Project
then transmitted commands to the Low Gain Antenna on the spacecraft.
The commands are hitting the spacecraft, but the CDU (Command Decoder
Unit) is not executing.  The station then swapped from CPA-2 (Command
Processor Assembly - 2) to CPA-4 and commands were again sent, but there
is still no executing by the spacecraft.  The 34 meter antenna at Goldstone
also provided support last night, but again there is still no command
execution by the spacecraft.  The Project will make a formal annoucement
later today.
