              SXT CHIEF OBSERVER'S REPORT AND TABLE PLAN

                  CHIEF OBSERVER'S REPORT for Week 06
			3-Feb-97 to 9-Feb-97
                         

SOLAR ACTIVITY

The Sun was quiet during the week.  There were many B-class flares, but 
only one C-class flare.  Three active regions were present (AR 8015, 8016
and 8017).  None of them produced hard X-ray flares, but all of them 
were associated with eruptions between 6-FEB-97 22 UT and 7-FEB-97 18 UT.

 
SXT INSTRUMENT STATUS

No problems last week except for an SEU at the last pass on 5-FEB-97,
which was recovered at the first pass next day.  SXT continues to 
function well.


CAMPAIGNS

No major campaigns during the week.


SEMINARS

The Yohkoh seminar resumed on 6-FEB-97.  The speaker and title were:

N. Gopalswamy (U. Md.)
"Coronal and Interplanetary Shocks"





                      SXT TABLE PLAN FOR WEEK 07
                       (10-Feb-97 to 16-Feb-97)

Because of MUSES-B launch (planned on 11-FEB-97) and its schedule uncertainty, 
no detailed plan can be made at this time.  

The dark calibration table is on Monday.  After Tuesday, we will decide
what to do on a daily basis.

* The first table is uploaded at pass 2 although originally planned for pass3,
which has been cancelled due to MUSES-B test operations.  


Continuing requests:

We request that KSC tohbans continue to dump a patrol image each time an
SXT table is loaded to facilitate the study of optimizing ARS parameters
during quiet times. 

SSOC TOHBAN, please e-mail any terminator schedule to the chief observer
(sxt_co@isass0) so that he can decide about filters and offpoints.  On
next week's visible diagram, please mark the official 5 passes first and 
then cross those passes that will be given to other satellites.
