                        MAGELLAN STATUS REPORT
                          November 12, 1990
 
     The Magellan spacecraft performance is nominal.   The spacecraft
successfully accepted commands on Friday, November 9, resuming mapping on
orbit 787 at 4:07 am PST on Saturday, November 10.  One STARCAL (star
calibration) occurs every orbit and 1 DESAT (desaturation of the reaction
wheels) every 4th orbit.  16 STARCALS and 4 DESATS have been done since
mapping resumed.
 
     A sequence patch to disable solar array control during mapping has
prevented the spacecraft vibration from recurring.  Track 1 of tape recorder B
was successfully played back on November 9.  It contains the results of
STARCALS performed during Superior Conjunction.
