The next timer setting is planned for 09-jun-97 (Monday evening). 2.3 Offpointing for Terminators None 2.4 HXT, BCS, and WBS calibrations None 2.5 Re-Definition of Normal Pointing Normal pointing OG (#32 dec) was re-defined on Jun 3, but the pointing position was slightly different from that expected. The normal pointing OG was re-re-defined on Jun 5. Hudson san, is the new pointing position correct? [Today, he and Seko-san will check the status of pointing.] 3. Errors and Problems 3.1 BCS Errors and Problems: None 3.2 SXT Errors and Problems: A bit map error occurred on pass 3, 6-Jun, and this error was recovered immediately by Yobi-Command within this pass. 3.3 Failed File Transfer from DSN. It seems that the the file transfer for the preliminary DNS schedule failed, because only Monday and Tuesday passes were included in the file. We got the preliminary schedule via RASM. [probably ftp failure] 4. DSN Communications: 4.1 DSN Final (Real-Time) schedule for W23: We cancelled 5 passes for W23. Most of them were due to lack of OP slots in the weekend OP. 4.2 DSN Final schedule for W24: We cancelled 6 passes for W24. They are either too low elevation (< 10 deg) passes or passes too close to another passes. 4.3 DSN Preliminary Schedule for W25: We cancelled 1 pass for W25. 4.4 DSN Strawman schedule for W26: We cancelled 35 passes. 4.5 Data Transmission from DSN: (/home/flare1/yohkoh/dsn_corrupt/97_23) 134 76 1040 not received Requested 21 May. no response Requested 27 May. no response Requested 30 May.

YOHKOH/ASUKA/AKEBONO/HARUKA Pass Conflicts at KSC: 5.1 Canceled passes for W23, W24 Week 23: Six passes were cancelled for Haruka Week 24: Seven passes were cancelled for Haruka 6. Special Operations: None. 7. Holiday Schedule: The next holiday will be Sunday, June 15. 8. Hikitsugi Items: 8.1 Tohbans for W24 SSOC : Shin, Slater KSC : Magara, Watanabe_H 8.2 OP and Command Sheet Status The command sheets and OP for Monday evening (09-JUN UT) have been sent to KSC . The OP has also been transferred to KSC. It is, however, still necessary to check tail_dsn. 8.3 STT Timer setting Due on Monday evening. An STT Timer setting was already included in today's evening operation (970609-0723). The tobans need to plan an STT Timer setting in a pass on 16 June (Monday). 8.4 New Manual and Checksheet Versions A new version of the English Tohban Manual is now out. Future tohbans (beginning with this week's) should write corrections and updates directly in the manual, and inform A. Sterling of the changes. Jim Lemen has made a new version of the checksheet to correspond to the new manual. Changes to the checksheet should be marked on the checksheet and reported to A. Sterling. 8.5 Sirius Data Nothing to report. 8.6 Suggestion to DSN selection rule: mail from JPL I understand that you access RASM and choose the passes that are made available to you. We would like you to use the Wallops (WFF) passes as much as possible. In other words, if a pass from one of the DSN sites (Goldstone, Madrid or Canberra) can be substituted by a WFF pass, please use the WFF pass and delete the DSN pass, instead of vise versa. Please understand we are not asking you to give up any coverage but if the same coverage can be accomplished by using WFF instead of the DSN, we would like you to do so. (Albert Chang) 8.7 Request from NEC Operator at KSC When a 'ROG' commamd are written on a command sheet, the command number should be written both in decimal and in hex. 9. Action Items None.
