----------------------------------------------------------------- SSOC Tohban's Report for Week 37 (08 Sep 1997 - 14 Sep 1997) ----------------------------------------------------------------- SSOC : H. Miyazaki & T. Shimizu KSC : S. Yasuno & M. Noguchi 0. Meeting attendance (in alphabetical order): No WOM was held due to the Day of Respect-for-the-Aged. 1. Solar Activity: Solar activity this week was moderate, with flares including an M1.0 on 8th September. Yohkoh observed the decaying phase of the M1.0 flare. There were 5 or 6 active regions in high latitude, some of which showed high activity. 2. Standard Operation: 2.1 SXT Table Uploads: The following SXT tables were uploaded last week. ------------------------------------------------------------ Pass ID Pass # Table ID ------------------------------------------------------------ Monday 970908-0722 1 970908 P1 ARS0 XBP 970908-0826 2 970908 P5 ARS1 STD Tuesday 970909-0930 3 970909 P3 ARS0 XBP Wednesday 970910-1030 4 970910 P4 ARS1 DKCAL Thursday 970911-0824 2 970911 P2 ARS1 JET 970911-1031 4 970911 P4 ARS1 DIFF Friday 970912-0928 4 970912 P4 ARS1 STD Saturday 970913-0825 3 970913 P3 ARS1 STD ------------------------------------------------------------ 2.2 STT timer setting: We set the STT timer during pass 2 on 9 Sep, Tuesday (970909-0826). The next STT timer setting is due on 16 Sep, next Tuesday. 2.3 Off-pointing for Terminators : None 2.4 HXT, BCS, and WBS calibrations : BCS had calibrations listed as follows: BCS Source Calibration, starting at 12:25UT, 12 Sep. BCS Stim Calibration, during pass 4 on 12 Sep (970912-0928). 3. Errors and Problems 3.1 SXT Errors and Problems: 3.1.1 SXT Errors none 3.1.2 SXT Table Cancelation The second table upload was planned at Pass 5 on 9 Sep, Tuesday, to return the XBP table to the standard table, but the table upload was canceled at KSC. This was caused by the lack of communication between KSC tobans and SXT CO. To mininize the lack of communication, a special fax form is now in prepation. 3.1.3 Imcomplete Patrol Image in Reformatted Database SXT_CO had reported that the patrol image dumped on pass 970911-0824 was incomplete. No HXT CAL was made at that time. The mainframe software tells the patrol image was downlinked without problem. The reformatter may be suspected. 3.2 BCS Errors and Problems: None. 4. DSN Communications: 4.1 DSN Final schedule for W37: 4 passes were canceled, 3 of which are because of the lack of OP slots in the weekend operation, and one is due to too low elevation. 4.2 DSN Final schedule for W38: 10 passes were canceled, most of which are too close to another passes. 4.3 DSN Preliminary Schedule for W39: 11 passes were canceled, most of which are too close to another passes. 4.4 DSN Strawman schedule for W40: 26 passes were canceled, most of which are too close to another passes. None of these were due to conflicts with ASCA. 4.5 Data Transmission from DSN: (/home/flare1/yohkoh/dsn_corrupt/97_37) 237 76 1219 not received Requested 29 Aug. no response Requested 02 Sep. no response Requested 05 Sep.

KSC Pass Conflicts and Schedule 5.1 YOHKOH/ASCA/AKEBONO/HALCA Pass Conflicts at KSC: Week 37: 3 passes were canceled due to conflict with HALCA. Week 38: 6 passes will be canceled due to conflict with HALCA and AKEBONO. 5.2 Future Schedule: Nothing to report. 6. Special Operations: None. 7. Holiday Schedule: The next holiday will be 21 Sep, Sunday. 8. Hikitsugi Items: 8.1 Tohbans for W38 SSOC : N. Saita & S. Tsuneta KSC : M. Noguchi & S. Sano 8.2 OP and Command Sheet Status The command sheets and the OP for Monday (15-Sep-97) have been created. 8.4 OPOGNEW instead of OPOGEDT ----Paraphrased from the previous week's report ---------------------------- We continued to use the revised version of OPOGEDT, OPOGNEW. OPOGNEW is the same as OPOGEDT except that the printing out of the OP is simpler. The SSOC tohbans should press the PF4 key (`print') on the mainframe and then print out the OP by typing: IDL> print_op ***** NOTE ******* Similarly, in order to print out the OG, type: IDL> print_ogall IDL> print_ogsel ***** These softwares are not available. See A/I ****** It is also possible to use the mainframe emulator on flare20 instead of the mainframe terminal for some situations: flare20% telnet mainf1 17 s88239 ex op(opognew) PF3 is {Esc}3 PF4 is {Esc}4 etc. --------------------------------------------------------------------------- 8.5 STT_PLOT ----Paraphrased from the previous week's report ---------------------------- It is possible to check the STT Tracking by using the routine `STT_PLOT': First make sure you are on the HOME directory of the yohkoh account then type: IDL> stt_plot (,'DD-MM-YY') This will plot a time variation of the STT output signal level. If the STT is working properly, the signal level should stay in between 400--800, and should vary only in the time period set by the timer. See sample plots in the tohban's manual. --------------------------------------------------------------------------- 8.6 New Manual and Check sheet Versions ----Quoted from the previous week's report --------------------------------- A new version of the English Tohban's Manual is now out. Future tohbans 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 check-sheet to correspond to the new manual. Changes to the check-sheet should be marked on the check-sheet and reported to A. C. Sterling. --------------------------------------------------------------------------- 8.7 Sirius Data Nothing to report. 8.8 Suggestion to DSN selection rule: mail from JPL ----Quoted from the previous week's report --------------------------------- 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 vice 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) --------------------------------------------------------------------------- 8.9 Power Down of Main Frame The main frame will be downed from 09:00(JST) to 16:00(JST) on 21-Sep(Sun) . 9. Action Items 9.1 Further software development It would be greatly appreciated if the SSOC tohbans could recommend any software development that they think will save future tohbans time and which improves the reliability of their. 9.2 Week-35-A/I-1 SSOC tohbans The SSOC tohbans should inspect the horizon maps sent by JPL and think about whether it would be possible to determine whether the acceptable minumum altitude (Is 10 degrees really the best estimate or is less accepatble?). Please refer to Hudson-san for further information. 9.3 Week-37-A/I-1 /Hudson/status open The following IDL softwares do not work well. Hudson-san will fix them. IDL> print_ogall IDL> print_ogsel end of report
