Yohkoh/ASCA Pass Conflicts at KSC ---------------- 2 passes in W31 were lost to ASCA. 4 passes in W32 are scheduled to be lost to ASCA. 6. Special Operations ---------------- There were no special co-ordinated campaigns in W31. Special BCS operations `BCS Detector on at Night' are scheduled for Mon 05-Aug-96 and have already been put in the OP. 7. Holiday Schedule ---------------- The next KSC holiday is 11-Aug-1996. 8. Hikitsugi Items ---------------- 8.1. Tohbans for W32 ---------------- SSOC: N. Saita & K. Akita KSC: Masahiro Takahashi & Suzuki 8.2. STT Timer setting ---------------- The next setting should be on 06-Aug-96 JST. 8.3 Sirius Data As Katano-san will be absent in W32, if there is a problem with the Sirius data during W32 a SIRIUS tohban will call the SSOC tohbans. In such a case please request retransmission of the data from DSN. 8.4. Op_first_guess LOS Medium/High Mode. ---------------- The op_first_guess fails switching to the medium mode during the KSC passes in the OP plan when there are canceled passes. Alphonse Sterling sent a note to Jim Lemen about this and the SSOC tohbans suppose Jim is working on this. In the meantime, tohbans should be careful to check the KSC LOS mode in the next day's operations in the OP. 8.5. RASM switched to flare20. ---------------- The RASM script, krasm, now works on flare20, but not flare11. 8.6. Flare1 printer ---------------- The new printer next to the flare1 workstation does not accept plain- text files' printing jobs, but works only for PostScript files. Most of printing jobs from flare20 were resumed to work, but it still needs modification of scripts. Report to the software managers, if you notice any problem. The jobs to printout new DSN schedules automatically don't work correctly. We should do this manually.
