The joint observation with SPARTAN --------------------------------------- As we had the joint observation with SPARTAN last week, we carried out some offpoint opearations. 6. DSN Communications ------------------------------------------------------ 6.1 DSN Strawman Schedule for W40 The strawman schedule for w40 arrived on Friday, and it happened that there was no DSN conflict in the schedlue, so we did not have to meet with Drs. Itoh and Skinner (ASCA) for w40. 6.2 Re-transmission Request. On 14,15-Sep-94, the datasets of 14 and 15-Aug-94 which we re-...-requested arrived. But the datasets from 0107 to 0118 and from 0616 to 0625 are not perfect, so we requested the re-transmission. 6.3 ISAS gateway The ISAS gateway was down on 12 Sep, so we couldn't receive the dataset. The ISAS gateway was rebooted. But after that the ISAS gateway was sometimes down , we requested to the gateway manager to reboot it. 7. Yohkoh/ASCA Pass Confilicts -------------------------------------------- Three KSC passes were lost during week 37 because of conflict with ASCA (Pass_5 of 12,16 and 17-Sep-94). And two passes will be lost during week 38 (Pass_5 of 20 and 22-Sep-94). 8. Holiday Schedule ------------------------------------------------------- The next horiday will be on 25-Sep-94. 9. Hikitsugi Item --------------------------------------------------------- 9.1 Tohbans for Week 38 SSOC: H. Watanabe and Y. Kozuka KSC: S. Sano and K. Morimoto 9.2 STT Timer Set The next STT timer set is due on Tuseday (20-Sep-94). 9.3 Please add offpoint commands to OPs We got some offpoint images last week, because we had the joint observation with SPARTAN. We need some offpoint terminator images, so we have to add the offpoint command to OPs during the campaign observation mode this week.
