SOHO Daily Meeting Minutes for Monday 25 August 2003 ANNOUNCEMENTS ------------- * Failover testing on SOC machines during the DSN gap tomorrow from 1030-1330 UT. * Voice loop outage on Wednesday from 4 PM until midnight EDT. * Current RHESSI default target is AR10436. When selecting this target to maximize coordination w/others, use campaign number 6850. * Goddard BW Parkway Bridge will be closed from September 3, 2003 until February 2004 for restoration. FOT REPORT ---------- Spacecraft Status: Nominal: Inverted roll position HGA position monitoring disabled. Spacecraft Anomalies: 234/1752 Multiple SUMER mnemonics violated yellow limits during door operations. Impacts unknown. Accomplished Activities: DOY 234: VIRGO, RSL DOY 235: SWAN DOY 236: NONCOHO_03236 Planned Activities: New tracking star, mag = 7.2 Upcoming Operations: ACU/CDMU Memory Dumps planned for 9/2 Ground Anomalies: 235/1404 CMS POCC socket terminated and was unavailable for 4 minutes, cause unknown. 235/1619 Lost 2 minutes 33 seconds of unrecoverable TLM, possibly due to a TCP failure at D66. 235/1831 Received 6.5 minutes of degraded TLM from D16 due to a line overflow at SPC-10. CHANDRA was also flowing high rate data at the time. Lost data recoverable from the CDR. 236/0150 Received 6 hours 35 minutes of degraded TLM from D46 due to a low SNR. Data from 0158 to 0216, and 0810 to 0825 is recoverable from the SSR. All other lost data is unrecoverable. 236/0339 Lost 1.5 minutes of TLM, 5 minutes of CMD ability, and 22 minutes of range data due to an exciter failure at D46. 236/1220 String 4 workstation 1 hung during post-pass operations, cause unknown. String 4 unavailable for one day until GSE could correct problem. 236/1050 DPS hard drive failed due to a hardware problem. Impacts TBD. 237/1003 Received degraded TLM from D66 between 1003 and 1015 due to a low SNR. All lost data is recoverable from the SSR.
