----------------------------------------------------------------- SSOC Tohban's Report for Week 38 (15 Sep 1997 - 21 Sep 1997) ----------------------------------------------------------------- SSOC : S. Tsuneta & N. Saita KSC : M. Noguchi & S. Sano 0. Meeting attendance (in alphabetical order): H. Hara, J. I. Khan, Y. Ogawara, N. Saita, S. Savy, M. Sawa, M. Shimojo, T. Watanabe, J. -P. Wuelser 1. Solar Activity: Solar activity continued to be moderate. The GOES X-ray level was at mid-B. Later this week, two M-class flares and some C-class flares occured. Yohkoh observed some of the flares on Sep 19 and 20. 2. Standard Operation: 2.1 SXT Table Uploads: The following SXT tables were uploaded last week. ------------------------------------------------------------ Pass ID Pass # Table ID ------------------------------------------------------------ Wednesday 970917-0824 4 970917 P4 ARS1 DKCAL Thursday 970918-0722 4 970918 P4 ARS1 STD Friday 970919-0515 2 970919 P2 ARS0 JET 970919-0722 4 970919 P4 ARS1 STD Saturday 970920-0516 2 970920 P2 ARS0 JET 970920-0723 4 970920 P4 ARS1 STD ------------------------------------------------------------ 2.2 STT timer setting: We set the STT timer during pass 3 on 17 Sep, Wednesday (970917-0721). The next STT timer setting is due on 23 Sep, Tuesday. 2.3 Off-pointing for Terminators : None 2.4 HXT, BCS, and WBS calibrations : None 3. Errors and Problems 3.1 SXT Errors and Problems: 3.1.1 SXT Errors none 3.1.2 SXT Table Cancelation The tables that were planned to be sent at the fourth pass on 15 Sep and the second pass on 16 Sep were canceled because of the typhoon. 3.2 BCS Errors and Problems: One BCS error occured at the fifth pass on 17 Sep(970917-0928). The error was recovered during the next pass at the second pass on 18 Sep(970918-0515). 4. DSN Communications: 4.1 DSN Final schedule for W38: 1 overbooking DSN pass was canceled because of the lack of OP slots in the weekend operation. 4.2 DSN Final schedule for W39: 5 passes were canceled, these were too close to other DSN passes. 4.3 DSN Preliminary Schedule for W40: 4 passes were canceled, these were too close to other DSN passes. 4.4 DSN Strawman schedule for W41: 39 passes were canceled, these were too close to other DSN passes. None of these were due to conflicts with ASCA. 4.5 Data Transmission from DSN: (/home/flare1/yohkoh/dsn_corrupt/97_37) 245 76 0431 corrupted tape Requested 05 Sep. corrupted tape Requested 09 Sep. no response tape Requested 12 Sep. no response tape Requested 17 Sep. no response Requested 19 Sep. 246 80 0450 corrupted tape Requested 05 Sep. corrupted tape Requested 09 Sep. no response tape Requested 12 Sep. no response tape Requested 17 Sep. no response Requested 19 Sep. 246 76 0632 corrupted tape Requested 05 Sep. corrupted tape Requested 09 Sep. no response tape Requested 12 Sep. no response tape Requseted 17 Sep. no response Requested 19 Sep. 255 76 0046 not received Requested 19 Sep. 256 76 0104 corrupted tape Requested 19 Sep. 256 80 0430 corrupted tape Requested 19 Sep. 259 76 2252 corrupted tape Requested 19 Sep. ** DOY-255 74 1620 No dump received(16-Sep.:E-mail from JPL) DOY-258 80 0332 No dump modulation during support.(16-Sep.:E-mail from JPL) 4.6 DSN scheduling interface tasks change Starting next week, September 21, 1997, the scheduling interface tasks for Yohkoh and ASCA will be shifted from DSN to the Wallops Flight Facility (WFF). We need to add the following people to your E-mail mailing list. Debbie Dukes Dukes@woss1.wff.nasa.gov Office (757)824-2186 FAX (757)824-2403 Rick Jones Jones@woss2.wff.nasa.gov Office (757)824-1774 FAX (757)824-2403 Wallops Realtime Operations wotssl@pop800.gsfc.nasa.gov (757)824-2375 FAX (757)824-2403 5. KSC Pass Conflicts and Schedule 5.1 YOHKOH/ASCA/AKEBONO/HALCA Pass Conflicts at KSC: Week 38: 6 passes were canceled due to conflict with HALCA and AKEBONO. Week 39: 10 passes will be canceled due to conflict with HALCA and AKEBONO. 5.2 Future Schedule: There were a long-term planning meeting with Nagase-sensei and the representatives of all four satellites on 18 Sep. 6. Special Operations: A typhoon approached KSC on Monday to Tuesday. There was no operation from the second pass on Monday to the fourth pass on tuesday. So, there was typhoon recovery operation on the fifth pass on Tuesday (970916-0827). 7. Holiday Schedule: The next holiday will be 28 Sep, Sunday. 8. Hikitsugi Items: 8.1 Tohbans for W39 SSOC : H. Hara & J. Wuelser KSC : S. Sano & Y. Iizuka 8.2 OP and Command Sheet Status The command sheets and the OP for Monday (22-Sep-97) have been created. And the OP has already trasfered. 8.3 flare20 WS The WS of flare20 had been in trouble since Friday. When we used idl on flare20, the idl was in demonstration mode. (i.e. after a few minutes, the idl did 'exit' automatically.) Now, the trouble has already fixed. 8.4 OPOGNEW instead of OPOGEDT ----From W37 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 ----From W37 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 ----From W37 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 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) --------------------------------------------------------------------------- 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 work. 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
