FOT REPORT
----------
Spacecraft Status: Nominal
Spacecraft Anomalies:
292/2123 Unexpected BDR Status - Battery 1 BDR 1 off.
Accomplished Activities:
DOY 292: VIRGO, CELIAS
Acquired new tracking star, mag = 6.55
DOY 293: VIRGO, SWAN, CELIAS, Flight S/W Maint.
DOY 294: VIRGO, CELIAS, Noncoho Load
Planned Activities: VIRGO
Acquire new tracking star
Switch Battery 1 BDR 1 on
Upcoming Operations:
11/7 MM and SK Operations
11/14-15 Roll Maneuver
Ground Anomalies:
292/2025 Lost 9 seconds of TLM and 8 minutes 52 seconds of
command ability due to D46's antenna off-pointing
as the result of an ATS2 failure.
293/0746 Received degraded data during entire D66 support
(0746 to 1550; 8 hours 4 minutes). Cause unknown.
293/2205 Lost 1 hour 9 minutes of range data and 39 minutes
of command ability as D46 was unable to lock
spacecraft receiver #1 due to incorrect sweep
parameters.
294/0739 Received degraded data during entire D66 support
(0739 to 1151; 4 hours 12 minutes). Cause unknown.
295/1019 Tracking star in slot 2 went false event as its
Z-coordinate crossed beyond the SSU's field of
view. Star was made ineligible and released until
a new tracking star can be provided by FDF.

INSTRUMENT STATUS
-----------------
CDS: Nominal. See MEDOC report.
SUMER: Nominal. See MEDOC report.
UVCS: Nominal. Today UVCS has 10 hours of special observations
starting at 16 UT, 4 hours of synoptics and 10 hours of
special observations. Tuesday at 16 UT UVCS begins
24-hour synoptics.
LASCO: Nominal. C2 and C3 synoptics.
EIT: Nominal. Half resolution 195 Angstrom CME watch and synoptics.
MDI: Nominal. Full disk magnetograms and dopplergrams, supporting
AR moss study.
TRACE: Nominal. Looking at AR 9661 and AR moss study with Sac Peak.
MEDOC Daily meeting - Monday 22-October-2001
--------------------------------------------
P Lemaire showed some results of SUMER's off-limb (by 30") observations
from Friday. The OVI lines had a good S/N and a ratio of ~2.5, allowing
the line formation process to be identified. Scattered light will be
determined from the Lyman-beta line data.
Brigitte Schmieder reported that THEMIS had observed the flare in AR9691 on
Sunday (21-Oct 11:20 UT). CDS was observing that region, but had not observed
any part of the flare directly.
A Gabriel reported that a filament eruption in the north-west on Saturday,
20-Oct, (as also notified by J Gurman) had changed the structure of the
streamers in that region, which had been the subject of JOP 130.
After consulting the latest images it was decided to set the SUMER slit to
X=170" at the change scheduled for today (22-Oct)

MEDOC detailed daily plan for Tuesday 23-Oct-2001
SUMER
-----
Slit position will be at X=170"
JOP 133 00:00 - 03:30 On disk line profiles. (170",134")
JOP 131 08:00 - 12:00 Lyman lines study. Filament (170",134")
JOP 122 15:00 - 19:30 Heating blocks. (170",0")
JOP 130 19:30 - 24:00 Streamer study (170",960"). Useful extra data even
though no UVCS support
available.
CDS

UVCS
----
- 16:00 continuing 10 hr special + 14-hr long synoptic
16:00 - 40:00 10-hr special + 4-hr mini-synoptic + 10-hr special
EIT
---
Usual CME watch
TRACE
-----
Support requested for JOP 149 and JOP 122, but apparently it is conditional
upon commitments to GB programs, which are conditional upon the weather.
THEMIS
------
THEMIS support ends on Tueday, 23-Oct.
