Meeting Attendance no meeting -------------------------------------------------------------- 1. Solar Activity Solar activity was slightly increased than last week. One M-class flare occured on 28th Feb. and several C-class flares occured subsequently. -------------------------------------------------------------- 2. Standard Operations 2.1 SXT Table Uploads The following SXT tables were uploaded during week 10: ===================================================== UT Date Pass Table ID ===================================================== 1-MAR-99 4 990301 P4 ARS1 DAR (*) 2-MAR-99 2 990302 P2 ARS1 DIF (*) 3-MAR-99 2 990303 P2 ARS1 STD (*) 4-MAR-99 2 990304 P2 ARS1 STD (*) 5-MAR-99 2 990305 P2 ARS1 STD (*) ===================================================== 2.2 STT Timer setting STT timer was set during pass 4 on 01-Mar-99 (UT). -------------------------------------------------------------- 3. Errors and Problems 3.1 BCS Errors: None. 3.2 SXT Errors: None. 3.3 NASA Tracking Stations: Nothing to report. 3.4 DP Error A DP error (error code = 90) occurred during pass 990303-1134. KSC tohban could not make a contact to Fujitsu/Nomura-san within that pass, so KSC tohban and Nomura-san cleared the error during pass 990303-1547. However, REPRO and IMG CHK at passes 990303-1134/990303-140 were finished normaly. 3.5 KSC A400 error On 5-Mar., there was trouble on the hard disk of the A400 at KSC. PB data of passes 1,2,5 were recoverd from S3500 and transfered later to SSOC. We confirmed that the SIRIUS data was created late in the day. -------------------------------------------------------------- 4. Special Operations 4.1 Tohban workstation flare20 restored Shimojo-san renamed flare27 to flare20 so it renewed. New flare20 was tested already and seems to work regularly. If one meets any problem during work on flare 20, tell Shimojo-san about it. -------------------------------------------------------------- 5. NASA Station Scheduling 5.1 Contact pass cancels/adds The following DSN/NASA passes were added/deleted: =================================================================== DSN/NASA Schedule Week Schedule Changes =================================================================== Final 11 6 passes deleted by SSOC Preliminary 12 0 passes deleted by SSOC Strawman 13 88 passes deleted by SSOC (12 passes deleted due to ASCA conflicts) =================================================================== 5.2 Data Transmission from NASA Ground Stations -(From /home/flare1/yohkoh/dsn_corrupt/99_10)------------ 046 46 1045 6% data loss Requested 19 Feb Closed/ same data. 047 82 1634 corrupted tape Requested 19 Feb no response tape Requested 24 Feb Closed/ correct data 047 80 1958 corrupted tape Requested 19 Feb no response tape Requested 24 Feb Closed/ correct data 054 80 1500 corrupted tape Requested 01 Mar Closed/ same data 054 76 1643 corrupted tape Requested 01 Mar Closed/ same data ## Hudson_san requested me to send the re-transmission request of DOY-054 data.

KSC Pass Conflicts and Schedule In week 10, 4 KSC contacts to ASCA, and 2 to GEOTAIL. In week 11, 4 KSC contacts to ASCA, and 3 to HALCA. -------------------------------------------------------------- 7. Hikitsugi Items 7.1 Tohbans for week 10 SSOC: S. Masuda, Te. Watanabe KSC: A. Shiozawa, Takanashi 7.2 STT timer setting STT timer setting is due on Tuesday, 9-Mar-99 (JST) 7.3 Holiday Schedule All days for week 11 will be business day. The next holiday will be 15-Mar (JST) in week 12. ====== The following is the same as the previous week's report. ====== 7.6 Manual and Checksheet A new version of the English Tohban Manual was generated during the week, along with a corresponding new Tohban Checksheet. The new (and all future) Tohbans are requested to note any changes or mistakes in the manual, and to notify A. Sterling of the changes. If the changes involve the DSN procedures or the ~yohkoh/wallops/README file, Hugh Hudson san should also be notified. Please include your name (or initials) next to your suggested corrections. Current Version Yohkoh Tohban Duties Manual Rev. 1-Feb-99, A. Sterling README (Manual for Wallops/DSN Operations) Ver.5.2 28-Sep-98, H. Hudson The Japanese SSOC Tohban Manual was last modified on 23-Nov-98 by Ishii and Ichimoto san-tachi. 7.7 Some Problems in OP_FIRST_GUESS - NASA tracking passes Hudson san has modified DSN_INPUT.PRO to take care of an op_first_guess problem in picking up some NASA passes occurring near 0 hours UT (see week 98_37 SSOC report for a detailed description of the problem). All seems to be fine now, but for a while Tohbans should double check that all the passes assigned to us by NASA in the latest final schedule are actually included in the OP. - Maximum Elevation In determining zenith passes, Tohbans should use the maximum altitude listed in the Weekly Visible Diagram, rather than the value on the command sheets. (See week 99_04 SSOC Tohban report for more details). 7.8 DSN Pass Additions (from week48_98 report) Pass addition requests can now conveniently be made (preferably at the Preliminary Schedule stage) using the add_dsn routine. See the wallops directory README file, and the Tohban Manual section on DSN Scheduling. ---------------------------------------------------------------------------- 8. Action Items 8.1 Further software development. Status CONTINUING. 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. 8.2 Week-48-A/I-1 /Hudson/status AJAR. PRINT_OGALL still does not work well. Hudson will fix it. === END ===
