Errors and Problems ------------------------------------------------------- 3.1 SXT errors None. 3.2 BCS errors None. 3.3 Software update In order to accomodate leap years, SXT QL software on flare5 was updated by Shimizu-san as of 18 Jan. 4. DSN Communications -------------------------------------------------------- 4.1 DSN Final schedule for W03 We canceled 2 DSN contacts from the final schedule for W03. 4.2 DSN Final schedule for W04 We canceled 4 DSN contacts from the Final schedule for W04. 4.3 DSN Preliminary schedule for W05 We did'nt canceled any DSN contacts from the Preliminary schedule for W05. 4.4 DSN Strawman schedule for W06 We canceled 42 DSN contacts from the Strawman schedule for W06. 4.5 Pass additions None. 4.6 Re-transmission requests and results Katano-san requested re-transmission of the following passes : DOY 014 14-JAN-96 08:15-08:59 DOY 014 14-JAN-96 04:59-05:43 DOY 015 15-JAN-96 06:35-07:35 DOY 015 15-JAN-96 19:38-20:22 DOY 016 16-JAN-96 02:12-02:57 DOY 016 16-JAN-96 21:39-22:21 DOY 017 17-JAN-96 00:40-01:23 DOY 017 17-JAN-96 02:31-03:15 DOY 017 17-JAN-96 04:14-04:57 DOY 017 17-JAN-96 18:33-19:17 DOY 017 17-JAN-96 20:16-21:00 DOY 017 17-JAN-96 23:24-00:10 5. Yohkoh/ASCA Pass Conflicts at KSC ----------------------------------------- In W03, 5 passes were lost due to conflicts with ASCA. 6. Special Operations -------------------------------------------------------- 6.1 BCS Calibration BCS Calibration was done on 19-JAN-96. BCS SOURCE CAL between pass 2 and pass 3. BCS STIM CAL at pass 4 7. Holiday Schedule ----------------------------------------------------------- The next holiday will be on Sunday, 28-Jan. 8. Hikitsugi Items ----------------------------------------------------------- 8.1 Tohbans for W04 KSC : K.Hori and S.Yashiro SSOC: M.Sawa and M.Miyashita 8.2 STT timer setting The next STT timer set is due on 23-Jan-96 JST. 8.3 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. 8.4 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. 8.5 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. 8.6 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 8.7 20m Antenna maintainance 20m Antenna will be shut down due to the maintainance from 7 a.m. to 10 a.m. on 24-JAN-96 (JST). But Yohkoh operation will not be affected, because the operation is to start at 1 p.m. 8.8 Layout change of computers in the operation room The layout change of computers in the operation room (the 3rd floor in B-toh) will be done from 8 a.m. to 4 p.m. (JST) on 29-JAN-96. ------------------------------- End of Report ---------------------------------
