              SXT CHIEF OBSERVER'S REPORT AND TABLE PLAN

                  CHIEF OBSERVER'S REPORT for Week 04
			20-Jan-97 to 26-Jan-97
                         

SOLAR ACTIVITY

The Sun was very quiet last week with only a few small active regions
visible.  There was one B-class flare on 20 January. 

SXT INSTRUMENT STATUS

The SXT instrument remains in fine working order.

CAMPAIGNS

A campaign to observe streamers in collaboration with
SoHO spacecraft ended on 22 January. 

SEMINARS

There were no Yohkoh seminars in Week 4.





                      SXT TABLE PLAN FOR WEEK 05
                       (26-Jan-97 to 02-Feb-97)

This week may be a quiet week, since we are not aware of SoHO campaigns
at the time of writing.  But we are flexible enough to accomodate a
last minute request.  If we do not hear from anybody, I would like to 
stare at a region over the week end for a CME.

The dark calibration table will have to be postponed to Thursday because
of a irregular spacecraft holiday on Wednesday.  The weekly diffusers are
included as part of a standard table on Friday.

 *** Please note that this table plan may change during the week. ***
 *** Please note that I will go back to a naming convention where the
     date is referred to the UT date of the first pass.  ***

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.
