Errors & Problems ------------------------------------------------------- 4.1. Error for SXT table upload SXT table wasn't uploaded at Pass 2 on 14-NOV-95 because of following reasons : 1. SXT C.O. pushed the wrong key and sent the file to upload the entire table instead of just the changes. That is why the table was too big to upload in a single pass. 2. SXT C.O. also somehow made 2 copies of the command file and no copies of the compare file. The recovery for this error was completed at Pass 1 on 16-Nov-95. 4.2 SXT Error SXT error, JERR:ST RDY & UERR:SHUTTER, occured at Pass 1 on 17-Nov-95. The recovery for this error was completed at Pass 2 on 17-Nov-95. 4.3 BCS Error None. 5.

Hikitsugi Items --------------------------------------------------------- 9.1 Tohbans for Week #47 KSC : Y.Hanaoka, K.Shibata SSOC : T.Sakao, T.Magara 9.2 STT Timer Setting The next STT Timer should be done before 25-Nov-95 (Sat). 9.3 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 to be edited appropriately. 9.4 Transmission of OP You don't need to confirm the transmission of OP/OG files to KSC on the console on 3rd floor. But when you or KSC Toban find a failure in transmitting them, please note the times when the OP was created and transmitted to KSC and report them to Shuto-san and Kosugi-san. (See w44_95-Appendix-A) 9.5 SXT Patrol Image Dumps The command `DP BC "8C 05(Hex)"' should be executed whenever an SXT table upload occurs. This command dumps an SXT patrol image which is needed to check the ARS parameters since the Sun is very quiet. 9.6 "KSC LOS OG" of the second(next) day KSC passes Last week, "op_first_guess" showed us the following OP draft. (1) Case of week end (Friday => Saturday): KSC LOS (QT HI) ;<= Last 3 KSC LOS on the second day. << skip >> KSC AOS-[A/B]-[DAY/NT] ;<= Last 2 KSC AOS << skip >> KSC LOS (QT ME) ;<= Last 2 KSC LOS QUIET RATE HIGH KSC AOS-[A/B]-[DAY/NT] ;<= Last KSC AOS << skip >> KSC LOS (QT ME) ;<= Last KSC LOS OP STOP (2) Case of the other day: KSC LOS (QT HI) ;<= First KSC LOS on the second day. << skip >> KSC AOS-[A/B]-[DAY/NT] ;<= Second KSC AOS << skip >> KSC LOS (QT ME) ;<= Second KSC LOS OP STOP We should modified the results of "op_first_guess". First KSC LOS =>; KSC LOS (QT HI) => modify to (QT ME) << skip >> <= insert "QUIET RATE HIGH" Second KSC AOS=>; KSC AOS-[A/B]-[DAY/NT] << skip >> Second KSC LOS=>; KSC LOS (QT ME) OP STOP "QUIET RATE HIGH" is necessary not only the case of before "KSC AOS-[A/B]-DAY" but also the case of before "KSC AOS-[A/B]-NT". Becouse if "KSC AOS-[A/B]-NT" was selected, it might be changed Night=>Day during the KSC pass. We also propose to examine that "QT H" command (Not "MANU QT H") is inserted in "KSC AOS-[A/B]-[DAY/NT]" OG. In the log of last few weeks, sometimes "KSC LOS (QT HI)" was seleceted, sometimes "KSC LOS (QT ME)" was seleceted. 9.7 ISAS Main frame computers schedule All of ISAS Main frame computers(M770/10#1,#2, M1800/20, VPP) will be stopped from (Sat)16-Dec-95, 09:30(JST) to (Mon)18-Dec-95, 00:00(JST) for maintenance. 9.8 End/New year Holidays for SSOC and KSC 28-Dec-95 - 4-Jan-96 (strawman(?)) ----------- END of Report ----------------
