SOHO Daily Meeting Minutes for Tuesday, 13 February 2001
FOT REPORT
----------
Spacecraft Status: Nominal
Spacecraft Anomalies: None
Accomplished Activities: VIRGO, CELIAS
Planned Activities: VIRGO, CELIAS, RSL
Upcoming Operations: 2/22 Momentum Management/SK Maneuvers
Ground Anomalies:
043/1700 AOS was nine minutes late as D24 had to reboot
their Block V Receiver and the RCC. Data
recoverable from the SSR. Nine minute delay in
commanding activities.
044/0830 AOS with D66 was 14 minutes late due to an antenna
controller malfunction. Executed unplanned
transitions to IDLE and RECORD. No data loss,
except ~45 minutes of potential MDI high rate TLM.

INSTRUMENT STATUS
-----------------
CDS: Nominal. Today - South pole Polarity reversal study and sunspot studies
on AR9339. Tomorrow - North pole Polarity reversal, sunspot studies with
TRACE/MDI (AR9339) and Network Studies. Thursday most likely CME Watch
in the South-West (AR9339).
UVCS: Nominal. UVCS continues its coronal hole study in the North-West
and mini-synoptics.
LASCO: Nominal. C2 and C3 synoptics.
EIT: Nominal. 195 Angstrom CME watch and synoptics. EIT observes that
the north pole coronal hole is visible for the first time in
three years.
MDI: Nominal. Today - Full disk and testing of a new line profile campaign.
Wednesday - sunspot study with CDS and TRACE. (06:34-07:50 UT
and 08:46-11:50 UT in full disk and 17:33-02:50 UT in high res mode)
TRACE times are: 10:30-15:30 UT.
TRACE: Nominal. We will continue tracking AR's 9339 and 9338 but now with
a bias toward 9338. Our weekend pointing was more centered on 9339 and
9338 was being frequently clipped. We are out of the "hard" eclipses
now but still re-targeting and stopping observations every orbit
since it may still be getting a bit dim for the targeting diodes.
We expect to stop this precaution on Wednesday but we will still
have EUV eclipses for a while. C IV may also still suffer dimming.
The observations are similar to our standard fare, no engineering.
We run a UV only flare watch for most of the day but do a 171/wl/1600
combo for 5 orbits. A UV North/South synoptic is also thrown in.
