                SXT CHIEF OBSERVER REPORT AND TABLE PLAN

                       SXT TABLE PLAN FOR WEEK 34
                        (21-AUG-95 to 27-AUG-95)

   The only coordinated campaign planned for this week is to assist
Hawaii in looking for filament eruptions. The observing objectives
of this plan are:
   - Standard filament observing table for half of the week.
   - Dark Calibration on Monday.
   - Continuation of terminator-offpointing campaign.

The SXT Table Plan for the week is as follows:

    KSC Time (start) in JST     Pass    Table ID        Comments
_____________(= UT + 9 hrs)______#_______________________________

Monday     21-Aug-95  17:33      2      950821 P2 ARS1 DARKCAL

Tuesday    22-Aug-95  17:52      3      950822 P3 ARS0 FILAMENT

Wednesday  23-Aug-95  18:11	 3	950823 P3 ARS0 FILAMENT

Thursday   24-Aug-95  15:05 	 2	950824 P2 ARS0 FILAMENT

Friday     25-Aug-95  15:24      2      950825 P2 ARS1 STD+LONG

Saturday   ************ NO TABLE UPLOAD PLANNED *************


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. 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 be used.  

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.

/// KSC and SSOC TOHBAN PLEASE NOTE:      \\\
\\\ THIS TABLE PLAN IS SUBJECT TO CHANGE. ///

   The SXT Chief Observer sees two possibilities in particular 
   this week.
   - The FILAMENT tables and STD+LONG tables may be re-arranged
     depending upon observing conditions and/or new information
     from our collaborators in Hawaii. This means that an SXT 
     Table ID may change within a day of the upload. HOWEVER, the
     SXT Chief Observer shall try to give the tohban EXTRA WARNING
     if the PASS # is to be changed.
   - There is a possibility that an SXT Table will be composed to
     look at the polar faculae, in conjunction with the proposal 
     of Koutchmy-san and Hara-san. The SXT CO will try to give the
     tohban ADVANCE WARNING if the upload schedule is to be changed.

SXT CHIEF OBSERVER'S REPORT for Weeks 32 and 33:  07-AUG-95 to
						  20-AUG-95

(This report spans Weeks 32 and 33 since there was no operations
 meeting for Week 33.)
The Sun has continued to remain largely quiescent for the past two
weeks.  There were no special operations except for some filament 
observations. We continued to concentrate on obtaining terminators 
with OG 85 (E08 S17) in all SXT filters, although lack of 
opportunities and a miscommunication between the SXT CO and the 
SSOC tohban negated this for the most part.

SOLAR ACTIVITY
Six active regions have transited the disk over this period. There
have been minor surges in activity according to GOES data, but 
nothing reaching C-level. The general depression in soft X-ray
emission has facilitated coordinated observing of filaments with
Mees.

SXT INSTRUMENT STATUS
The SXT has been functioning properly.

FILAMENT OBSERVATIONS
SXT has been assisting Hawaii with filament observations. There have
been a couple of near-successes, but nothing significant to report.

On the positive side, filament observations have provided the 
SXT Chief Observer with several learning experiences on the use of
ARS modes.

UPCOMING CAMPAIGNS
- SPARTAN
     Spartan 201-03 launch delayed until "late August".
     Our observing plan will change depending on exact launch date.

   - POLAR RAY CAMPAIGN
     The Yohkoh team has accepted a campaign proposal from Koutchmy-san
     and Hara-san to 
	"Identify and deduce relevant parameters of small 
        scale features seen at high temperature in polar 
        regions at time when polar faculae are still active."
     The dates of this campaign will be determined by the proposers and 
     the SXT Chief Observer.

PERSONNEL
- Hugh Hudson and Alphonse Sterling left ISAS in Week 33 to attend a
     high-energy conference at Goddard. The SXT CO felt lonely for a few
     days until ...

   - Greg Slater of Lockheed arrived 16-Aug-95 to handle Software and
     Systems duties.

SEMINARS

   - There have been no ISAS seminars recently.
