                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

SXT CHIEF OBSERVER'S REPORT for Week 16:   16-APR-96 to 21-APR-96

SOLAR ACTIVITY

Solar activity was low.  Two B-class flares occurred and there were several
small bright regions visible. A partial eclipse was observed on 17 April.

SXT INSTRUMENT STATUS

SXT was completely operational with no errors.

CAMPAIGNS

A special table was loaded on Thursday to observe two episodes of a partial
eclipse on 17 April UT.  The observations were successful.  Images and more
information on the WWW at
http://isasxa.solar.isas.ac.jp/~hudson/apr96.eclipse (and show_pix in IDL). 

A special table was loaded on 19 April (for one orbit only) to carry out an
SXT gain check. 

SEMINARS

The seminar for week 15 was by K. Shibasaki (Nobeyama Radio Observatory) on
"Radio Sources above a Flare Loop".



                       SXT TABLE PLAN FOR WEEK 17
                        (22-Apr-96 to 28-Apr-96)

There are no campaigns planned for this week.  The dark calibration table
will be loaded on Tuesday, and the weekly diffuser images included as part
of a standard table on Wednesday. 

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

    KSC Time (start) in JST     Pass          Table ID        
_____________(= UT + 9 hrs)______#_______________________________
 
Monday	    22-APR-96 20:09      2         960422 P2 ARS1 STD+LONG
Tuesday     23-APR-96 20:28      2         960423 P2 ARS1 DKCAL 
Wednesday   25-APR-96 00:13      4         960424 P4 ARS1 STD+DIFFU        
Thursday    25-APR-96 21:06      3         960425 P3 ARS1 STD+LONG 
Friday      26-APR-96 19:43      2         960426 P2 ARS1 STD+LONG
Saturday    27-APR-96 18:19      2         960427 P2 ARS1 STD+LONG


*** 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. 

  PREPARATION OF OGs: The following OGs need to be made this week, as soon
as possible.
