SSOC Tohban Report for Week 44 
                     (31 October - 6 November 1994)

  SSOC: T. Watanabe, H. Hudson 
  KSC : K. Fujiki, M. Akioka 

 1. Solar Activity ------------------------------------------------------------

 Solar activity remained at a rather low level. NOAA listed 22 B-class flares
 between 31-Oct and 3-Nov. The last C-class flare was on 29-Oct.

 2. Standard Operation -------------------------------------------------------- 

   2.1 SXT Table Uploads

   1 Nov: 941101 P3 ARS1 DKCAL
   2 Nov: 941102 P1 ARS1 STD+LONG
   3 Nov: 941103 P2 ECLIPSE/MSSTA
   4 Nov: 941104 P2 ARS1 STD+LONG

   2.2 STT Timer Set
     STT Timer was set on Tuesday (Pass_2 on 1-Nov-94).

   2.3 BCS stim cal, source cal
     Executed 4 Nov. 

   2.4 OG re-write
     The OG for S/C N (4') has been replaced by S/C NE (4'), which does
     a displacement E 4' and N 4' simultaneously. This was to optimize
     the eclipse observations for SXT.

 3. Special Operation -------------------------------------------------------

   Special operations were done to obtain observations during the eclipse
   and Hoover/Walker rocket on 3-Nov. These were partially successful, but
   an unfortunate error occurred before the rocket launch, and no simultaneous
   data were obtained. The eclipse was successfully observed in both FFI
   and PFI images. The SXT images show the footpoints of a coronal 
   streamer in the SW, which we hope was observed by the ground-based observers.

   Is there an ad hoc way in which the tohbans can extract data from the
   DSN gateway computer for temporary Sirius use? Many people were quite
   disappointed by this unfortunate timing. 

 4. Errors & Problem --------------------------------------------------------

   4.1 The AS-400 mini at KSC was down on Monday (31-Oct) and no real-time
       data could be seen at ISAS.

   4.2 flare1 presented many problems in the days prior to the 3-Nov special
       operation. Can we swap this old hardware for the new flare20 hardware?
       This computer is vital to operations and its poor hardware, coupled
       with poor maintenance, often causes problems.

   4.3 isass0 similarly continues to have major problems, perhaps associated
       with the /yd16 disk. Accordingly the weekly reformatting effort is
       falling behind.

   4.4 OP_FIRST_GUESS has had a couple of small problems over the last few
       weeks. One is that it may schedule OP START after the apparent point
       of 10 degree elevation (originally noticed by Yoshida_kun). We don't
       think that this is a real error, but please keep your eyes open and
       if you see a case like this, document it to Lemen_san. A second problem
       is that it may schedule a medium rate/high rate pair at night during
       an SAA. These commands are superfluous and are due, according to 
       Lemen_san, to a very complicated IF statement that he is fixin. Again
       keep your eyes open.

 5. DSN Communications ------------------------------------------------------

   5.1 DSN Cancellations and De-cancellations for W46

       Jose Valencia (DSN) sent e-mail announcing the cancellation of passes
       on DOY 319-324. We accordingly sent a fax request to reinstate some
       of the W46 cancellations made by the previous week's tohbans. The
       requested adds were:

       320 0619-0704 66 7976
       322 0418-0502 46 8005
       324 0456-0542 46 8035

   5.2 One DSN pass for Sunday was found to be at too low an elevation
       and was cancelled in real time (310/1528 66 #7833) by RASM.

   5.3 Re-transmission requests

       DOY 288 (Madrid) 20:24-20:22
       DOY 293, 298 (post-pass transmission fax reports only)

       None of these requested items had arrived.


 6. Yohkoh/ASCA Pass Conflicts --------------------------------------------

   The strawman conflicts for week 46 numbered about half a dozen, and
   were resolved at the Friday 2:00 pm meeting with Skinner_san of ASCA.

 7. Holiday Schedule ------------------------------------------------------- 
  
   The holiday will be on Saturday (12-Nov).
 
 8. Hikitsugi Items --------------------------------------------------------
  
  8.1 Tohbans for Week 44
    SSOC: Yasuno, Kano 
    KSC:  Akioka, Fujiwara

  8.2 STT timer setting
    The next STT timer set will be due on Tuesday (08-Nov-94).

  8.3 Preparation for the strawman DSN cancellations should be done
    prior to the Friday 2:00 p.m. meeting with ASCA. Hudson will be
    available for support.

  8.4 Please save relevant e-mail in the appropriate directory on flare1.
