4. STT Timer Set

  STT timer set was done on 11 May, Pass1. The next update should be done

5. Errors and Troubles

  (1) Although KSC toban must send a message about the error to BCS team 
     when the BCS error occurs, it didn't work last week. It seemed to be
     some network trouble. So the e-mail address of BCS was changed from 
     yohkoh@41887.dnet.nasa.gov   to
     yohkoh%ISASXA.dnet@isass0.solar.isas.ac.jp  .

  (2) SXT ERR
      May 10,  Filter Soft Error    --> recovered by FULL RECOVERY PLAN.
      May 12,  Ref. Data corruption --> recovered by Yobi A and FULL RECOV. PLAN.

  (3) op_first_guess and RASM.
      Once the resultant file of op_first_guess is made in mainframe, it could 
    not be overwritten even if we want some changes to correct some mistakes.
      We could not find the strawman schedule in /ydb/orbit_raw in spite of   
    the success in taking it from RASM. It was due to the change of directory in
    the disk according to Morrison san.
