Yoshida & T. Kosugi KSC : J. Ogura & S. Yasuno 0. Meeting attendance (in alphabetical order): H. S. Hudson, J. I. Khan, T. Kosugi, H. Miyazaki, M. Sawa, T. Shimizu, T. Watanabe, J. -P. Wuelser, T. Yoshida 1. Solar Activity: Solar activity increased. The GOES X-ray background is mid-B-level. There were several GOES C-class flares and 1 GOES M-class flare. The 'active' active region 8076 decayed and went behind the limb on 6 Sep. 2. Standard Operation: 2.1 SXT Table Uploads: The following SXT tables were uploaded last week. ------------------------------------------------------------ Pass ID Pass # Table ID ------------------------------------------------------------ Monday 970901-1032 2 970901 P2 ARS1 STD Tuesday 970902-1239 4 970902 P4 ARS1 DKCAL Wednesday 970903-1033 3 970903 P3 ARS1 STD+DIFF Thursday 970904-1030 2 970904 P2 ARS1 STD Saturday 970906-1031 3 970906 P3 ARS1 STD ------------------------------------------------------------ 2.2 STT timer setting: We set the STT timer during pass 2 on Tue. 2-Sep (970902-1032). The next STT timer setting is due on Tue. 9-Sep. 2.3 Off-pointing for Terminators : None 2.4 HXT, BCS, and WBS calibrations : HXT gain were re-adjusted during pass 3 on Tue. 02-Sep (970902-1136). HXT calibrations were done three times: during pass 3 on Wed. 03-Aug (970903-1033) during pass 3 on Thu. 04-Aug (970904-1030) during pass 4 on Thu. 04-Aug (970904-1134) 3. Errors and Problems 3.1 SXT Errors and Problems: Two bit map error was found. One was found in the pass '970903-0826', and cleared during the same pass with Yobi-C. The other was found in the pass '970906-0825' and cleared during the same pass. The patrol image dumped during 970903-1033 was incomplete. We dumped a patrol image again during 970904-0927. The patrol image dumped during 970904-1034 was incomplete again. We dumped a patrol image again during 970905-0824. This problem is now under investigation. 3.2 BCS Errors and Problems: None. 3.3 DSN Schedule File Transmission Problem: There were some problems sending schedule change requests to JPL via ftp. The ftp connection is now extremely bad. We did eventually manage to transfer the schedule change requests to JPL after many repeated attempts. Something should be done to help to improve the state of the network. Reminder: For file transmission to JPL via e-mail, one must use flare20. It is probably the only machine registered at JPL, i.e., flare14 cannot be used. 4. DSN Communications: 4.1 DSN Final schedule for W36: No cancelations. 4.2 DSN Final schedule for W37: No cancelations. 4.3 DSN Preliminary Schedule for W38: No cancelations. 4.4 DSN Strawman schedule for W38: 22 passes were canceled. None of these were due to conflicts with other satellites. 4.6 Data Transmission from DSN: (/home/flare1/yohkoh/dsn_corrupt/97_36) 237 76 1219 not received Requested 29 Aug. no response Requested 02 Sep. no response Requested 05 Sep. 245 76 0431 corrupted tape Requested 05 Sep. 245 16 1113 corrupted tape Requested 05 Sep. 245 16 1256 corrupted tape Requested 05 Sep. 246 80 0450 corrupted tape Requested 05 Sep. 246 76 0632 corrupted tape Requested 05 Sep. 247 76 0326 corrupted tape Requested 05 Sep. 5. KSC Pass Conflicts and Schedule 5.1 YOHKOH/ASCA/AKEBONO/HALCA Pass Conflicts at KSC: Week 37: 3 passes will be canceled due to a conflict with HALCA. 5.2 Future Schedule: Nothing to report. 6. Special Operations: 6.1 New S/C Normal Point (OG:32dec 20Hex) Command During the pass 970902-1343, the S/C normal point was slightly changed with the new S/C NML command made by H. Hudson-san. 7. Holiday Schedule: The next holiday will be Sunday 14-Sep. 8. Hikitsugi Items: 8.1 Tohbans for W37 SSOC : T. Shimizu & H. Miyazaki KSC : S. Yasuno & M. Noguchi 8.2 OP and Command Sheet Status The command sheets and the OP for Monday (08-Sep-97) have been created. 8.3 Sendmail Problem on flare14 Don't send e-mail from the flare14 machine. There are some problems in the sendmail system on flare14. 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 Similarly, in order to print out the OG, type: IDL> print_ogall IDL> print_ogsel 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. end of report
