                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

                       SXT TABLE PLAN FOR WEEK 25
                       (18-JUN-95 to  24-JUN-95)

This week should not be as hectic as last week.  We will do nothing 
special except for hunting filaments, depending on solar activity.
When a bright region appears, we may simply run a standard table.


The observing objectives of this plan are:
   - Dark Calibration on Wednesday.
   - The filament campaign with Mees Observatory.
   - Take offpoint terminator images.

The SXT Table Plan for the week is as follows.  Please remember that
this is subject to change.  The date in the table ID reflects the UT 
date of the first pass.

********************** KSC HOLIDAY ***************************


Terminator-Offpointing:
   The terminator-offpointing program will continue this week.  The 
SSOC tohbans are required to manually insert the off-point OGs for the 
terminators in the OP tables.  The SSOC tohbans, 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 be used.  

Dumping Patrol images:
   We request that KSC tobans 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.

SXT CHIEF OBSERVER'S REPORT for Week 23:  11-JUN-95 to 17-JUN-95

The two campaigns (Pic du Midi and Kitt Peak) went quite well even if 
an SEU-induced SXT error prevented an XBP table from being uploaded 
Friday morning.  Brigitte Schmieder is visiting Lockheed around 
Independence Day to make a first comparison of the data.
  

SXT INSTRUMENT STATUS

The SXT has been operating without major problem.  


PIC DU MIDI CAMPAIGN

We continued to focus on AR 7877 to the end of the campign, since no
other promising regions appeared.  Although we have to wait for DSN-
downlinked data to be reformatted to compare the SXT images with 
simultaneous Pic du Midi data, we saw in AR 7877 loop expansions (which
may have produced CMEs) as well as repeated brightenings.  We also tried
to observe a filament to the south of the region, but nothing
spectacular happened during our observations.

 
XBP CAMPAIGN

Some XBPs showed some structural changes, which should be compared 
in detail with the simultaneous Kitt Peak magnetograms.


UPCOMING CAMPAIGN

Spartan 201-03 is scheduled for launch on 30 July, followed by deployment
24.5 hours later.  It will observe solar corona for 43.5 hours.  I reminded
the UV team of the availability of SXT daily images at CRL, but we will be
contacted for more coordination.
