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.
