                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

SXT CHIEF OBSERVER'S REPORT for Week 07:   12-FEB-96 to 18-FEB-96

 
SOLAR ACTIVITY

The Sun was quiet all last week with no major flares.  For most of the week
we tracked a significant filament across the north of the disc that was
associated with a band of diffuse corona in the FFI images.  On Friday we
switched to automatic targeting of an active region that appeared on the
east limb.  This region exhibited an interesting X-type structure and
diffuse component above its main loops. 
 
SXT INSTRUMENT STATUS

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

CAMPAIGNS

Filament campaign during the most of 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 07.


                       SXT TABLE PLAN FOR WEEK 08
                        (19-Feb-96 to 25-FEB-96)

This week we will continue to observe the new active region on the east
limb during the main-frame computer replacement period (17-22 February).

On Friday we plan to change to the weekly dark calibration table for one
day. The weekly diffuser images will be taken as part of a standard table
on Saturday. The standard weekend table will be loaded during Sundays
passes as this is a 7 day week of operations. 


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

    KSC Time (start) in JST     Pass          Table ID

*** 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.
