SOHO Daily Meeting Minutes for Monday, 05 November 2001
ANNOUNCEMENTS
-------------
* We are back on the old router configuration since Friday at 2130 UT.
Due to the upcoming activities and holidays, it will be one or two
months before the upgrade is attempted.
* A proton event started shortly after the X1.0 flare on Sunday.
CDS is not safing. UVCS autonomous safing may be related.
CTOF limit violations prompted turning the instrument off and
switching on substitution heaters.
FOT REPORT
----------
Spacecraft Status: Nominal
Spacecraft Anomalies:
309/0431 UVCS mnemonics USMD went to "safe" and UUMTOMCV
violated YL limits. Cause believed to be proton
storm. Impacts TBD.
309/1123 CELIAS mnemonic FSCP5V violated YL limits for two
formats. Impacts TBD.
Accomplished Activities:
DOY 306: VIRGO, SWAN, RSL, Extra VC2 data collection
DOY 307: VIRGO
DoY 308: VIRGO, Flight S/W Maint, Noncoho Load
Planned Activities: VIRGO
Upcoming Operations:
Nov 3-19: X-panel heaters turn-off
Nov 7: SK/MM Maneuvers
Nov 9: Switch to DHSS Science Submode 5 (~1900 UTC)
Nov 14-15: Roll Maneuver
Ground Anomalies:
306/2343 Corrupted command resulted in a six minute delay of
NRT commanding, as seven commands retransmitted.
Cause unknown.
307/0203 CPA failure at D46 resulted in 25 minutes of lost
command ability. DR #C100550.
307/0138 LMC monitor data unavailable during D46 support for
2 hours 17 minutes. No impacts. DR #N100205.
307/0854 Received degraded telemetry during D66 support,
cause unknown. Degraded data occurred between 0854
and 1430. DR #N100213.
308/0700 Received degraded telemetry during entire D66
support, from 0700 to 1430. Cause unknown.
DR #N100214.
308/1806 Proton storm indentified using SEF counter
criteria. OE and EOF notified. Impacts TBD.
309/0025 Late carrier up due to a failed port card within
D46's LMC. Lost command ability for 26 minutes.
DR #C100552.
Other: None

INSTRUMENT STATUS
-----------------
CDS: Nominal. Full sun observations. Tomorrow: Cambridge AR/flare
campaign and safing for maneuvers at approx. 23:30 UT.
UVCS: Autonomous safe mode, cause yet undetermined. After diagnosing and
recovering, will start UVCS/Ulysses quadrature observations and
synoptic. Tomorrow: Ulysses coordination continues and safing for
maneuvers at approx. 23:30 UT.
LASCO: Nominal. High cadence until EIT finishes post-bakeout calibrations.
C2 and C3 synoptics. Safing for maneuvers Tuesday at about 21 UT.
EIT: Nominal, doing post-bakeout activities. Will start 195 Angstrom
CME watch and synoptics. High cadence observations begin Tuesday
night.
MDI: Nominal. Full disk magnetograms and dopplergrams. Tomorrow:
leg alignment.
TRACE: Nominal. Observing AR 9682.
