Errors and Problems ------------------------------------------------------- 3.1 BCS errors A BCS error occurred on 960218-1447. It will be recovered on Tuesday. 3.2 SXT errors There were no SXT errors 4. DSN Communications -------------------------------------------------------- 4.1 DSN Final schedule for W07 There were no cancellations from the final schedule for week 07. 4.2 DSN Final schedule for W08 There were 3 cancellations from the final schedule of week 08 due to too short intervals between the passes. 4.3 DSN Preliminary schedule for W09 There were 11 cancelations from the preliminary schedule for week 09. 4.4 DSN Strawman schedule for W10 There were 75 strawman cancelations for W10. 4.5 Pass additions None. 4.6 Re-transmission requests and results The following information is from files now kept on flare1 by Katano-san: flare1:/home/flare1/yohkoh/dsn_corrupt/96_07 034 17 2330 11% intermit data gaps Requested 5 Feb. 11% intermit data gaps Tape Requested 7 Feb. Closed/Data loss possibily due to DSN equip. problem. 13 Feb. 036 46 1202 Data not received. Requested 13 Feb. Closed/Pass deleted from DSN 7-Day schedule. 16 Feb. 039 66 0707 Data not received. Requested 13 Feb. Closed/Data available DR00004. 16 Feb. 042 76 1620 65% corrupted. Requested 13 Feb. e-mail(JPL) received 16 Feb/Data not received 16 Feb. The format for this dsn_corrupt file is still evolving. Tohban suggestions are still welcome. 5. Yohkoh/ASUKA Pass Conflicts at KSC ---------------------------------------- In W07, six passes were lost due to conflicts with ASUKA. We will lose six passes to ASUKA during W08. 6. Special Operations -------------------------------------------------------- None. 7. Holiday Schedule ----------------------------------------------------------- The next holiday will be on Sunday, 25-Feb. Week08 will have 7 successive operation days. 8. Hikitsugi Items ----------------------------------------------------------- 8.1 Tohbans for W08 KSC : R. Kano, S. Morita SSOC: K. Shibasaki 8.2 STT timer setting The next STT timer set is due on Tuesday, 20-Feb-96 JST. 8.3 Mainframe Replacement The mainframe computers will be unavailabe until the evening of 22 Feb due to replacement work. The OP files for 18-22 Feb have been already checked and transmitted to KSC. However, they are capable of modifying the OPs to some extent even at KSC. So, the SSOC tohban should immediately notify the KSC tohbans of the changes in DSN schedule etc. which need modification of OPs, preferably more than 24 hours prior to OP upload passes. The OP file for 23-Feb (Friday night) was also transmitted to KSC as a back up in case of a delay in the replacement. This OP is yet to be checked, though. 8.4 Offpoint terminator images If terminators appear in the OP generated by running OP_FIRST_GUESS, then the OP should be FAXed to the SXT_CO (Chief Observer) in D-toh. The SXT_CO will then inform the SSOC tohbans if offpointing will be carried out. If so, the OP will need be edited appropriately. 8.5 Transmission of OPs It is no longer necessary to confirm the transmission of OP/OG files to KSC by checking the printout on the 3rd floor in B-toh. Instead the time of transmission of the OP/OG files should be noted down. If the SSOC or KSC tohbans notice any failure in transmission of the OP/OG files then it should be reported to Shuto-san and Kosugi-san. 8.6 SXT patrol image dumps A block command `DP BC 8C-05 (hex)' should be executed whenever an SXT Table is uploaded. Since the Sun is very quiet, ARS parameters need to be checked by the SXT patrol images dumped by this command. 8.7 WWW server of DSN The DSN NOCC Information Server (NIS) is now on-line and available for DSN scheduling operations. The URL location is: http://dsn.jpl.nasa.gov/nss 8.8 New Password We now send strawman and preliminary DSN deletions to JPL by three methods: EMAIL, RASM, and FTP. A password is needed for the FTP transfer. Tohbans for the new week should get this password from the previous week's tohbans. 8.9 Manual Both of the Tohban Manuals have been updated, A. Sterling doing the English manual and K. Ichimoto doing the Japanese manual. There are several new procedures, mainly revolving around tail_dsn usage. Tohbans in the coming weeks should note places where explanations are inadequate. ------------------------------- End of Report --------------------------------
