Around 02:30 UT on February 5, 2002, SOHO went into Emergency Sun
Reacquisition (ESR) mode shortly after an interruption of the power
supply to one of the reaction wheels. Power to all the instruments was
also interrupted. Recovery from ESR mode into Coarse Roll Pointing
(CRP) mode took place at about 12 UT.

Instruments were turned back on, checked out, and safed in preparation
for a station keeping and momentum management manoeuvre which is
planned for Friday, February 8. Tomorrow, February 7, the spacecraft
will be put into RMW (Roll Manoeuvre Wheels) mode in preparation for
the manoeuvre.
