Meeting Attendance ---------------- N.saita, S.K.Savy, Kosugi, H.Miyazaki, Ogawara, Sterling, Watanabe, Hara, Yoshida 1. Solar Activity ---------------- Solar Activity remained low, but there were numbers of B-class flares and one C-class flare produced by NOAA AR 7981, which has been the primary target of the collaborative observation with SOHO. As this AR moved beyond the west limb, GOES base line declined by a factor of 3. There appeard a slow EFR near the disc center (NOAA AR 7982). 2. Standard Operation ---------------- 2.1.

Errors and Problems ---------------- 3.1. SXT Errors ---------------- Bit map errors were detected during the following passes. They were recovered by Yobi C command during each passes. 5-Aug-96 Pass 1 (960805-0618) 8-Aug-96 Pass 1 (960808-0414) 3.2. Monitor SA2 at KSC failed One of the monitors at KSC, SA2 failed on 06-Aug (Tue). Due to this, KSC tohbans couldn't check BCS errors. It seems to have repaired it- self on 08-Aug-96 (Thu). Replacement is needed, maybe. 4. DSN Communications ---------------- 4.1. DSN Final schedule for W32 ---------------- No passes were canceled. 4.2. DSN Final schedule for W33 ---------------- 15 passes were canceled. 4.3. DSN Preliminary schedule for W34 ---------------- 9 passes were canceled. 4.4. DSN Strawman schedule for W34 ---------------- The Strawman schedule for W34 did not arrive on Friday of W31, so the deletion was done in W32. We canceled 55 passes. 4.5 DSN Strawman schedule for W35 ---------------- As Katano-san was abscent, this will be done by next tohbans. 4.6 Data Transmission from DSN ---------------- As Katano-san was absent this week, this will be reported next week. * DOY 176 data was received at DSN (WALLOPS) on 24 June. The percentage of this data on SIRIUS is 0%. We requested retransmission of this data set many times, but there has been no response! How shall we proceed on this matter? 5. Yohkoh/ASCA Pass Conflicts at KSC ---------------- 4 passes in W32 were lost to ASCA. 4 passes in W33 are scheduled to be lost to ASCA. 6. Special Operations ---------------- 6.1 Change of off-point OG The offpoint OG #85 was changed on 6-Aug-96 from "S/C W.014N.232" to "S/C W5.12N.023". 7. Holiday Schedule ---------------- The next KSC holiday is 18-Aug-1996. 8. Hikitsugi Items ---------------- 8.1. Tohbans for W33 ---------------- SSOC: T.Kosugi & H.Miyazaki KSC: N.Suzuki & M.Shimojo 8.2. STT Timer setting ---------------- The next setting is due on 13-Aug-96 JST. 8.3 Sirius Data As Katano-san was absent in W32, strawman schedule arrangement for W35 ( and for W36 as well?) shall be done this week. 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. --- end of report ---
