     the same pass.

   4.2 Problems

     Last week's tohban forgot to mention that flare1 hung up on Feb. 25.
     Some files seemed to be damaged, judging from the error messages on
     disk check.

     New orbital data file was not created on the Lockheed machine.
     A side effect of the replacement of isass0 ?  It was fixed next day.


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

   5.1 DSN Strawman Schedule for W12

     We cancelled a total of 35 DSN contacts from the schedule.

   5.2 DSN Forecast Schedule for W11

     We cancelled a total of 0  (zero) DSN contacts from the forecast schedule.

   5.3 DSN Final Schedule for W10

     There was 9 cancellation for W10.

   5.4 DSN Final Schedule for W09

     We cancelled 1 DSN contacts from the final schedule.

     JPL cancelled 2 DSN contacts (DSS-46) due to a S/C emergency on TDRSS-1.
     There were no chances we could modify the OPs accordingly.

   5.5  Wallops station

     Wallops test operation has started this week.  There were 4 Wallops 
     contacts for W09.  Sirius people confirmed the validity of the first 
     downlinked data. The rest of the data are yet to be transferred/checked.

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

    In week 09, we lost the following three KCS passes due to pass conflicts
    with ASCA:

    950227-1343 (3rd pass of Feb.27, from 21:19 UT)
    950303-1239 (3rd pass of Mar. 3, from 19:10 UT)

 8. Hikitsugi Items --------------------------------------------------------

   8.1 Tohbans for Week10

      KSC  : Muranaka, Kobayashi
      SSOC : Nakajima, H. and Suga, K.

   8.2 STT timer setting

     The next STT timer set is due on Tuesday (Mar. 7).

   8.3 Wallops station

     SSOC tohban should carefully check the Wallops passes on the next-next
     weeks DSN final data.  Some contacts should be cancelled if the Wallops
     station starts standard operation.

     Since Wallops station is not taken into account by op_first_guess, SSOC
     tohban will have to modify OP command tables by hand.

     AOSLOS program at KSC is yet to be modified to incorporate Wallops st.
     Hence, SSOC tohbans should fax the AOSLOS list for Wallops to KSC.

     Nothing to report.
