SXT Status Report
			7 August - 13 August 1995 (Week 32)
                                  ---------

   To my mind, temperatures have cooled ever so slightly this past week,
perhaps due to cloud cover. All of that rain that Alexander made a
hallmark of his reports must have followed him back to Montana. I'm sure
the people there will thank him. . .


SOLAR ACTIVITY

   Activity levels have remained low, to no one's great surprise. Active
regions AR7894, 7895, and 7896 passed to the west limb, while only one
significant region has appeared at the east limb now at the end of Week 32.
The vast area of the disc between these shows a quiet corona which is much
less discernable by the SXT (i.e., lower emission of X-rays) than at more
active times. According to GOES data, solar activity has breached the 
B-level only a few times this week.
  

SXT INSTRUMENT STATUS

   No problems with the SXT this week.   
   In fact, there have not even been minor SXT Errors during KSC operations
   since June!

CALIBRATION STATUS

   The offpoint terminator program continues, theoretically.
   Practically speaking, no opportunities arose this week.


PASS CONFLICTS

   We lost a total of five (5) passes due to conflicts with ASCA.


CAMPAIGNS

   The only campaign carried on in Week 32 was Filament Observation
   with Hawaii.
   Following is the status of impending, or on-hold, campaigns.

   - FILAMENT OBSERVATIONS
     Contrary to last week's plan, some filament observations were carried
     out in Week 32. Specifically, SXT Table [950810 P2 ARS0 FILAMENT] was
     uploaded at (10-Aug-95 13:35) and "downloaded" ("unloaded"?) at
     (11-Aug-95 13:54). Times in UT. The filament it was set to observe
     (at roughly S15 W38) erupted only an hour or so before the Table went
     into effect. In accordance with the general depression now of solar 
     activity, the filament eruption was "weak". In soft X-rays, one can
     see some restructuring of the coronal fields, but an event of such
     magnitude would have gone unnoticed a couple of years ago.

   - SPARTAN
     Spartan 201-03 launch delayed until "no earlier than mid-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
     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.


SEMINARS

   Yohkoh seminar fans must continue to wait until the lecture series
   begins once more.

PERSONNEL

   No changes.

OPERATIONS NOTE:

   It was decided at the Weekly Operations Meeting for Week 32 that the 
   WOM for Week 33 (Mon. 14, Aug.) would be skipped. The next WOM will be 
   held Mon. 21, August.
