   2.2 STT Timer Set
     STT Timer was set on Tuesday (pass2 on Nov 08,94).

   2.3 S/C off pointing
     OGs during the KSC contacts
       Nov 09 pass2: East-8'
              pass3: West-8'
              pass4: normal pointing
     OGs in the OP, which are for the offpoint terminators
       Nov 09  03:53UT - 04:05  :  East-8' 
       Nov 11  07:47UT - 08:00  :  SE-8' 
       Nov 12  08:05UT - 08:20  :  South-16' 
       Nov 13  08:25UT - 08:40  :  West-8' 

   2.4 OG write
      SXT group (Hara san) added two commands, SXT DAY & SXT SHT CLOSE, in
      the SXT Halt Operation OG. This OG was written in pass1 of Nov 13.

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

   We started to collect the offpoint terminator images as listed in 2.3.
   This operation has to be continued in this week.

 4. Errors & Problems --------------------------------------------------------

   4.1 The discrepancy between the SXT tables of MS computer and the Yohkoh,
       discovered on Nov 4, was cleared by two SXT table uploads on Nov 08. 
       The cause, however, has not been understood yet. Fujitsu people may 
       request to simulate the situation that the this error occurred.

   4.2 The ASCA satellite went down to the safe hold mode on Nov 07, because
       the ASCA-KSC tobans confused the hexa-decimal number with the decimal 
       number and executed UVC-OG (the under voltage control). Because its
       recovary continued until Nov 10, the Yohkoh had only three KSC pass on
       Nov 10. The same trouble is likely to happen to the Yohkoh.
       During the ASCA recovary, there are two troubles of 20m antenna one is 
       in the side of the transmitter and the other is the receiver. We asked 
       the Yohkoh-KSC tobans to transfer ous the information of the antenna 
       condition when they get it.

   4.3 OP_FIRST_GUESS has had a couple of small problems over the last few
       weeks. The main problem is the timing of OP START, which is sometimes
       latter than the elevation 10 deg.

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

   5.1 DSN Scedules arrived in time.

   5.2 Re-transmission requests
         DOY 288 (Madrid) 20:24-20:22
         DOY 307 (Madrid) 12:45-12:57
     Because both of these were brocken, we requested the re-transmission.
     Until Nov.11, both had arrived and entered in SIRIUS.

   5.3 Data loss
         DOY 310 (Madrid) 15:28-15:36  : Nov 06
     This contact was deleted by JPL on Nov 04.
     SSOC tobans did not notice it.

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

   The strawman conflicts for week 48 numbered two, and were resolved at 
   the Friday 2:00 pm meeting with Skinner_san of ASCA.

 7. Holiday Schedule ------------------------------------------------------- 
  
   The holiday will be on Sunday (Nov.20).
 
 8. Hikitsugi Items --------------------------------------------------------
  
  8.1 Tohbans for Week 46
    SSOC: K.Yaji, H.Koshiishi 
    KSC : T.Fujiwara, K.Hori

  8.2 STT timer setting
    The next STT timer set will be due on Tuesday (Nov.15), 94).

  8.3 Offpoint terminator images
    Add the offpoint OG and the normal pointing OG in the OP during the 
    terminator manually.
 
  8.4 Negotiation with ASCA
    Negoticate the KSC contacts in the next week with Nagase san on Thursday,
    and the conflict in the strawman DSN schedule with Skinner san at the
    Friday 2:00 p.m.
