SOHO Daily Meeting Minutes for Tuesday 17 February 2004 ANNOUNCEMENTS ------------- * The current RHESSI default target is AR10554. When selecting this target to maximize coordination w/others, use campaign number 6850. * CMS testing tomorrow at 19 UT during the gap in DSN contact * EIT shutterless tomorrow so NRT will be limited FOT REPORT ---------- Spacecraft Status: Nominal Inverted roll position Spacecraft Anomalies: 048/1230 Single DMA Failure Over One Format during heavy UVCS commanding. Single packet failed to be acquired by COBS. Accomplished Activities: DOY 044: VIRGO, CELAIS, RSL, New tracking star, mag = 7.80, New tracking star, mag = 7.85 DOY 045: SWAN, CELIAS DOY 046: CELIAS, NONCOHO_04046 DOY 047: New tracking star, mag = 6.45 Planned Activities: RSL, SWAN, New tracking star, mag = 7.3 Upcoming Operations: None Ground Anomalies: 044/1950 SH4CM2 (prime CMS) GUI crashed, cause unknown. No direct operational impacts. 045/0910 Received degraded TLM from D66 between 0910 and 0940 due to a MFR problem. Lost data from 0910 to 0935 recoverable from D34, 0935 to 0940 unrecoverable. Integrity of 0936 magnetogram TBD. 045/1000 Lost 6 minutes of unrecoverable TLM, 155 minutes of CMD ability, and 179 minutes of range data due to an interlock transmitter error at D66. D54 brought up for replacement support from 1100 to 1300, after which D66 had repaired their system and resumed scheduled support. 045/1423 Received degraded TLM from 1423 to 1437 due to RFI at D66. Any lost data is unrecoverable. Possibly lost 1424 MDI magnetogram. 046/0848 Lost 4 minutes of CMD ability due to D34 prematurely terminating their uplink to RCVR-1. Swept into RCVR-2 to complete pass activities. 046/1012 Lost 1 hour 44 minutes of CMD ability due to an exciter failure at D66. 047/0910 Received degraded TLM from 0910 to 0921, and lost TLM from 0918 to 0920, due to a TCP failure at D66. Any lost data is unrecoverable. Other: None SOLAR STATUS ------------ 02/13 DOY 044 - 02/17 DOY 047 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20040217.html LASCO daily On-Line Solar Status and observations: http://lasco-www.nrl.navy.mil/observations/Todays_obs.html Web Page for Planning: http://www.bbso.njit.edu/arm Magnetic Maps and Heliospheric Forecasts: http://www.lmsal.com/forecast/ INSTRUMENT STATUS ----------------- CDS: Nominal.
