                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

SXT CHIEF OBSERVER'S REPORT for Week 06:   5-FEB-96 to 11-FEB-96

 
SOLAR ACTIVITY

The Sun was quiet all last week with no major flares.  We spent part of
the week tracking a significant filament across the north of the disc that
was associated with a band of diffuse corona in the FFI images. 
 
SXT INSTRUMENT STATUS

No significant SXT errors occurred.  SXT continues to function normally.

CAMPAIGNS

We returned to the filament campaign during the week.
Correspondents:  R. Canfield, K. Reardon, A. Kiplinger, L. Jiao, H. Zirin
Purpose:  to observe filament channels and possibly catch eruptions with
          SXT in a configuration for good time resolution.
  

SEMINARS

There was no seminar in week 06.


                       SXT TABLE PLAN FOR WEEK 07
                        (12-Feb-96 to  19-FEB-96)

This week we will continue to observe the filament on the north of the
disc.  On Wednesday we will do a DKCAL table.  The standard FFI diffuser
images (both low8 and compressed) will be taken on Thursday as part of a
quiet corona table. 

Quiet corona observations are scheduled for Thursday but if a suitable
filament is visible we will make that the PFI target. 

On Friday at pass 2 a standard ARS1 table will be loaded. This will be used
until the new mainframe computers are installed (17-22 February) and new
SXT tables can be prepared. Long exposures will not be included in this
table.

This week we continue with the terminator program, but no new OG's need to
be prepared.

The provisional SXT Table Plan for the week is as follows:

*** Please note that this table plan may change ***


Dumping Patrol images:
   We request that KSC tohban continue to dump a patrol image each time an
SXT table is loaded to facilitate the study of optimizing ARS parameters
for an awfully quiet period. 

  SSOC TOHBAN, please fax the preliminary OP list to D-tou when it contains
a terminator so that the Chief Observer can suggest which OG's to use.
