Errors and Problems 3.1 SXT Errors and Problems No SXT error. 3.2 BCS Errors No BCS error. 4. DSN Communications: In W02, there were significant delay in the delivery of preliminary(w04) and strawman(w04,w05) schedule from JPL. In W02, there were significant delay in the delivery of strawman(w04) and so preliminary(w04) and strawman(w05) did not arrive from JPL. 4.1 Cancellations for W02: We cancelled 5 DSN passes because of elevation of less than 10 deg. 4.2 DSN Final schedule for W02 and W03: We cancelled 9 DSN passes(W02). We cancelled 7 DSN passes(W03). 4.3 DSN Preliminary schedule for W03 and W04: 29 passes were cancelled from W03 preliminary schedule. The preliminary schedule(w04) did not arrive in W02 4.4 DSN Strawman schedule for W04 and W05: The strawman schedule(w04) was significant delay in the delivery at 11-Jan. The strawman schedule(w05) did not arrive in W02. 4.5 Data Transmission from DSN: (Status: See /home/flare1/yohkoh/dsn_corrupt/97_XX) 5. YOHKOH/ASCA/AKEBONO and MUSES-B Pass Conflicts at KSC: Week 02: 3 passes were cancelled. Week 03: 11 passes were cancelled for MUSES-B and 1 pass which is elevation of less than 10 degree was added. 6. Special Operations: none. 7. Holiday Schedule: The next KSC holiday is 20-Jan (Mon) JST. 8. Hikitsugi Items: 8.1 Tohbans for W03 SSOC: M. Shimojo and R.Canfield KSC: J. Koyama and K.Yoshimura 8.2 STT Timer setting The next STT Timer setting is due on 14-Jan (UT). 8.3 Sirius Data Nothing to report. 8.4 Yohkoh and Muses-B KSC conflict (1-DEC-96 - 1-FEB-97) Due to preparations for the launch of Muses-B the following is a list of passes expected to be lost by Yohkoh and proposed holidays: DAY(JST) COMMENT 15-JAN-97(Wed.) 3 passes loss 16-JAN-97(Thu.) 4 passes loss 17-JAN-97(Fri.) 3 passes loss 20-JAN-97(Mon.) Holiday 21-JAN-97(Tue.) 4 passes loss 22-JAN-97(Wed.) 4 passes loss 23-JAN-97(Thu.) Holiday 28-JAN-97(Tue.) Holiday 8.5 KSC workstation network crash. The Network which connect between KSC workstations was down on Jan 6. Thus SSOC tohban had to check 'SXT table write' from Sagamihara. But that trouble recovered next day. 8.6 KSC network construction KSC network rearrangement construction will work during Week 03. 9. Action Items 9.1 Week-42-A/I-1 /Hudson, Lemen, Yoshida/ status: DEFERRED UNTIL JIM'S VISIT T. Yoshida has produced preliminary software to aid in optimizing the Yohkoh DP rate in OPs. The final implementation of Yoshida san's software will probably have to await the next visit to ISAS by Jim Lemen. 9.2 Week-35-A/I-1 /Ogawara, Hara/ status: DEFERRED An action item to investigate the cause of recurrent problems with of the S-3500 computer at KSC has been deferred because no problems have occurred for several weeks. The investigation will continue if and when further problems recur. As FACOM's interim message, Ogawara-sensei reported that the GBIB board might be problematic. If that might be the case, he would see it is would be possible to have another board from a computer in Tsuruta-san's Lab, which we borrowed during the initial operations of Yohkoh. 9.3 Week-01-A/I-1 /flare WS Manager status(shimojo): CLOSE In week 01, the krasm program on flare20 hung-up several times. We rebooted flare20. Then the krasm problem did not occur in week 02.
