Hikitsugi Items -------------------------------------------------- 9.1 Tohbans for Week 21 KSC : Y.Kato and T.Ishii SSOC : H.Miyazaki and H.Hara 9.2 ASCA/SFU pass conflicts (KSC) Please contact Nagase-san (ex.2611) on Thursday(13:30) to decide when and how to negotiate week 22 pass conflicts with ASCA. 9.3 DSS-74(Santiago) and KSC pass conflicts for Strawman Schedule On Thursday's negotiation about KSC pass conflicts for W22 , we will also discuss about pass conflicts at Santiago station on W23 strawman schedule. At that time, discussion about Santiago passes will be based upon situation of KSC pass conflicts. SSOC Tohban may be required to check the pass conflicts on W23 also. Please consult with Hara san. 9.4 Strawman cancel for week 24 The meeting for week 24 strawman cancellations will be held on this Friday (26 May) as usual. 9.5 STT timer setting Please determine when STT re-start. 9.6 About the way of sending new orbital elements to JPL JPL no longer wishes to receive the YOHKOH orbital elements by FAX. They would like to get them by e-mail.About this issue we got some e-mail. We filed them in English Tohban manual temporally. 9.7 Terminators. The terminator-offpointing program will be continued this week.The SSOC tohbans will be required to manually insert the off-point OGs for the terminators into the OP tables following to suggestion by SXT_CO. After OP_FIRST GUESS, SSOC tohbans should send drafts of OP to SXT_CO at D-tou. SXT_CO will send a request about terminators and associated offpoints if necessary. We are using the following offpoint OG's and are going through them in sequence cyclically. That is, change each time to the next number please: OG 33 S/C W19 S01 (all OG numbers are decimal) OG 34 S/C W17 N00 OG 35 S/C W10 S01 OG 36 S/C W04 N00 OG 85 S/C W03 N02 OG 86 S/C E04 N00 OG 87 S/C E18 N00 10 Santiago station issue Downlink at Santiago station will be available from about the end of May. Expected contact time for Santiago station is very close to KSC pass. Then, it shuold be useful when KSC contact is lost owing to conflict with ASCA/SFU. Hara san is making various efforts about this item.
