Hikitsugi Items ----------------------------------------------------------- 8.1 Tohbans for W02 KSC: J. Sato and E. Ueta SSOC: S. Nagata and S. Yuda 8.2 STT timer setting The next STT timer set is due on 08-Jan-96 JST at the first pass.. W02 SSOC Tohbans: Please carry out the STT Tracking check using the saplot as soon as possible. 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 ------------------------------- End of Report ---------------------------------
