COMMENT:

In view of increasing solar activity, the planned darkcal table is 
postponed until tomorrow or the day after tomorrow.  The FFI sequence 
of this table is a standard one, with the terminator image taken in Be 
filter.  The PFI sequence is slightly non-standard.  The Image in high 
telemetry mode is in 3 (EW) x 2 (NS) mosaic, to be prepared for a 
possible eruption (who knows?) around AR 8185.  In the flare sequence, 
a full resolution image is added before large FOV images to detect the 
first brightening within the flare region.


PLAN:

The next table will be pass 3 on Wednesday (1-Apr-98 12:51 UT).
The ID will be 980401 P3 DARKCAL.
