                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

SXT CHIEF OBSERVER'S REPORT for Week 02:   8-JAN-96 to 14-JAN-96

 
SOLAR ACTIVITY

The Sun was quiet during most of the last week with no major flares. 
AR7939 was visible for most of the week, but by the end of the week there
were no active regions on the disc. 

SXT INSTRUMENT STATUS

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

CAMPAIGNS

With the successful launch of the Flare Genesis balloon on 7-Jan-96, SXT
observations concentrated on AR739 for most of the week.  Due to various
problems, however, the Flare Genesis telescope could not track AR7939 as
intended, and remained pointed at disc centre.  

On Friday a special table was loaded to observe a filament at N50 in the
PFIs.  This was the start of a return to our unofficial quiet corona
campaign for the time being. 
  
SEMINARS

On Wednesday 10 January there was a regular Yohkoh seminar.  The speaker
was H.  Negoro (ISAS) on "X-ray fluctuations in black hole candidates in
comparison with solar flares". 





                       SXT TABLE PLAN FOR WEEK 03
                        (15-JAN-96 to 22-Jan-96)

James Lemen will take over as SXT Chief Observer this week.

This week we will continue to coordinate with the Flare Genesis Balloon
as appropriate.  The balloon payload is currently looking at Sun center.
The SXT partial field-of-view will also be set to Sun center unless an
active region or a good filament target appears.

The standard FFI diffuser images (both low8 and compressed) will be taken
on Thursday as part of a standard table.  The dark calibration table will
run over Tuesday night.  

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:

    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.
