SOHO Daily Meeting Minutes for Monday, 22 April 2002

ANNOUNCEMENTS

————-

* RHESSI target for today is AR 9906; target for tomorrow TBD.

* Sac Peak target for today is AR 9912; target for tomorrow

  is 9912.
* JOP104 target for today is AR 9906; target for tomorrow

  is 9907/9906.
* Science seminar on Wednesday 24 April at 3:30pm in the

  EAF. Speaker Nat Gopalswamy will speak on Solar Energetic

  Particles and Interacting CMEs.
* D27 is expected to come up on Wednesday, so the only

  impact expected is a 35 minute gap on Tuesday.
* We will change to the new CMS as our prime one today.
FOT REPORT

———-

Spacecraft Status: Nominal

		   CDS, SUMER safed due to proton storm
Spacecraft Anomalies: 111/0932  CELIAS mnemonic FSCMCPV violated YL

			        limits for two formats.  Impacts TBD.
Accomplished Activities:

DOY 109:        VIRGO, CELIAS, RSL, New tracking star, mag = 5.8

DOY 110:        VIRGO, SWAN

DOY 111:        VIRGO, Noncoho Load, Flight S/W Maint.
Planned Activities: VIRGO, New tracking star, mag = 7.2
Upcoming Operations:    May 1st ACU/CDMU Memory Dumps
Ground Anomalies:

109/1927        Lost 5 minutes 56 seconds of unrecoverable TLM,

                cause unknown.  DR #G101046.

109/2000        Received degraded TLM from 2000 to 0108 due to a

                router problem at JPL.  Data should be recoverable

                from the CDR.  DR #N100384.

110/0026        Pass activities delayed 20 minutes 9 seconds due to

               ¢»ÏPA failure at D46.  DR #C101134.

110/1143        Accidental removal of the SOHO link from the LMC at

                D66 caused an unrecoverable loss of TLM for 6

                minutes 52 seconds, and lost command ability for 10

                minutes 34 seconds.  DR #M100676.

111/0153        Proton Storm caused increased activity in the SSR

                SEF counter and the SSU.  EOF personnel notified.

                CDS, LASCO, and SUMER safed due to magnitude of

                this proton storm.

111/0704        Degraded TLM received real-time over the big pipe

                due to an overload of the little pipe.  Data

                degraded from 0704 until 0729; any lost data is

                unrecoverable.  DR #N100386.

111/1603        SH4XT2 hung due to a problem with the cctrend

                script used during clock correlation.  Rebooted

                X-terminal and turned problem over to GSEs.

112/0352        Lost 2 minutes 18 seconds of unrecoverable TLM due

                to a TCA failure at D46. DR #C101138.

INSTRUMENT STATUS

—————–

CDS:	Nominal. Not observing due to proton storm. Hope to resume

	observations this evening. Plan for tomorrow is to do AR/flare

	diagnostics on AR9912, support JOP104, support JOP155, and do

	some engineering studies.
SUMER:	Nominal. Not observing due to proton storm and high counts. Hope to

        resume observations tomorrow morning and continue JOP104 on AR9907/9906.
UVCS:	Nominal. JOP155 and mini-synoptic for today and tomorrow.
LASCO:	Nominal. C2/C3 synoptics, supporting JOP155.
EIT:	Nominal. Half-resolution 195 CME watch and synoptic, supporting

	JOP155.
MDI:	Nominal. Full disk magnetograms and dopplergrams for

        continuous contact, supporting Sac Peak campaign.
TRACE:	Nominal. Support RHESSI (AR9906), JOPs 104/137 (9906) &

	154 (9912), and Sac Peak (9912). Tomorrow is TBD, but will

	probably be similar.
