SOHO Daily Meeting Minutes for Monday, 22 January 2001 ANNOUNCEMENTS ------------- - Just to inform people, last week we transitioned over completely to the SOHO DPS for telemetry. As a result, the corresponding directories that contained ECS DPS data have been deleted. - Tuesday 23 January from 12noon - 1pm the EAF network will be down. They are performing tests of a new switch. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: 020/0314 CEPAC ESU Data Request Error. Recovered autonomously. CEPAC ESU non-operational for ~3 minutes; other impacts unknown. Accomplished Activities: 019: VIRGO, RSL, OCD #1470: Extra VC2 for MDI 020: CELIAS, VIRGO 021: VIRGO, SWAN, Flight S/W Maint. Planned Activities: VIRGO, New tracking star, mag = 7.4 Upcoming Operations: 01/29 TR Maintenance 02/08 Off-pointing Maneuvers Ground Anomalies: 019/1906 Command corrupted between the antenna and the spacecraft, resulting in a 6 minute delay of NRT activities as a total of nine commands were retransmitted. 020/1036 Ground receivers at D66 lost lock on the downlink resulting in theloss of 1 minute 26 seconds of unrecoverable real-time data. Since an SSR dump was taking place at the time, the lost portions of the VC4 data were redumped. 020/1510 Scheduled D24 support was replaced by a D27 support, as DSN required the 34 meter resources elsewhere. Lost 6 hours and 50 minutes of scheduled range data. 020/1510 AOS 52 minutes late as station operators lost the ability command the antenna. Lost 52 minutes of potential MDI high rate data, and 52 minutes of commanding time.
