OPERATIONS ENGINEER(S): C. Maroney / R. Yurow
SCIENTIST: I. Ugarte
CDS INSTRUMENT: 
  SOHO had a warm startup at 15:45 UT. 
  SOHO returned to medium rate at 18:43 UT.
  The science plan was halted at 21:21 UT so that submode transitions (plus
patching) can take place to return to submode 6. A transition to submode 5
was made at 21:32 UT.  A transition to submode 6 was made at 21:43 UT.  CDS
is nominal after submode transitions.
  Due to lack of time before the plan was to start (00:00 UT), the plan
load at 23:24 UT had to be aborted at 23:58 UT.
  SYNOP was deleted from the plan.  The new science plan will resume 
at 03:20 UT.
CDS GROUND SYSTEM: 
  The IWS command rate was reset to 1/10s for commanding on DSN-27.

CDS INSTRUMENT: 
  The DCS was cleared manually to upload a modified science plan at 12:30 UT.
  AT 12:31 UT, The CDS OBT was updated via RCR command.
CDS GROUND SYSTEM: 
  Due to scheduled NRT for CDS being late, there was not enough time to load
the prepared science plan.  The plan was modified to start JOP 166 at
13:30 UT.  Science plan upload was successful.
