Holiday Schedule ---------------------------------------------------------- 7.1 Next holiday Next holiday will be on Sunday, 10-Dec-95. 7.2 New year holidays(fixed) The last operation of this year will be on the morning of Dec. 29. New year holidays begin from Dec. 29 PM (JST). The beginning of Yohkoh operations in 1996, it will be started from Jan. 4 evening. 8. Hikitsugi Items ----------------------------------------------------------- 8.1 Tohbans for W49 KSC: Y.Suematsu and S.Ueno SSOC: H.Nakajima and J.Khan 8.2 STT timer setting The next STT timer set is due on 8-Dec-95 (Fri). 8.3 New year holidays schedule At the beginning of this week new year holidays schedule will be fixed. The schedule will be informed from Nagase san of ASCA to SSOC tohbans. Please contact him for more information, if necessary. 8.4 Request from JPL on Yohkoh schedule change SSOC tohbans received the following e-mail from Jose Valencia of JPL. ..................................................................... Date: 21 Nov 1995 14:31:38 -0800 From: "Jose Valencia" To: "katano@flare1.solar.isas.ac.jp", "lemen@isass1.solar.isas.ac.jp", "yohkoh@flare1.solar.isas.ac.jp" Cc: "Donna E Dillard" , "Bruce W Pivar" , "Stefan Waldherr" , "Leonard F Weinberg" Subject: YOHKOH schedule change requests. Dear Sir, The preferred method to communicate YOHKOH schedule change requests is by either E:mail or RASM. If FAX transmission is necessary the YOHKOH schedule changes must be sent to 584-4516 which is located within the DSN scheduling department. Please note; Schedule change requests must no longer be sent to 393-0612 which is the NOCC. Your cooperation in this matter is greatly appreciated. Regards, Jose Valencia. ...................................................................... 8.5 Offpoint terminator images If terminators apper in the OP generated by running OP_FIRST_GUESS, then the OP should be FAXed to the SXT_CO (Chief Observer) in D-toh. The SXT_CO will then inform the SSOC tohbans if offpointing will be carried out. If so, the OP will need be edited appropriately. 8.6 Transmission of OPs You no longer need to confirm transmission of OP/OG files to KSC by the MS console in the B-toh 3rd floor. Instead, if you or KSC tohbans notice any failure in transmitting the OP/OG files, please record creation/transmission times of the files and report them to Shuto-san and Kosugi-san. (c.f. W44_95 SSOC Tohban Report Appendix-A) 8.7 SXT patrol image dumps A block command `DP BC 8C-05 (hex)' should be executed whenever an SXT Table is uploaded. Since the sun is very quiet, ARS parameters need be checked by SXT patrol images dumped by this command. 8.8 KSC-LOS OG for the second (next) day KSC passes In preparing draft OPs with the OP_FIRST_GUESS, we sometimes encountered the well-reported QUIET RATE HI/MED confusion in KSC-LOS OGs for the second (next) day KSC passes. However, we may be able to carefully check the draft OPs and choose the appropriate bitrate in each case. This problem does not seriously affect S/C operations. ------------------------------- End of Report ---------------------------------
