SOHO Daily Meeting Minutes for Monday 15 March 2004 ANNOUNCEMENTS ------------- * Due to the scheduled EIT bakeout and TRACE engineering, there will be at least 1.5 days without any full disk EUV data for planning, starting Thursday at about 00 UT. * The current RHESSI default target is AR10570. When selecting this target to maximize coordination w/others, use campaign number 6850. * We have looked at data from a shadow track performed by ESA's New Norcia station, which might conceivably be used for some future keyholes. The data does not contain Reed-Solomon data, causing DPS to flag the LZ products as bad (the quality accounting packages at the end of the telemetry files will flag the failed Reed-Solomon check). Does this affect the data processing for any of the teams? If so, let us know. We do not recommend spending time to circumvent the problem at this time, though. FOT REPORT ---------- Spacecraft Status: Nominal Inverted Roll Position Spacecraft Anomalies: None Accomplished Activities: DOY 072: VIRGO, RSL, New tracking star (mag 6.5) DOY 073: MDI DOY 074: SWAN, NONCOHO, Timetag load for weekly activities Planned Activities: UVCS safing activities Upcoming Operations: Keyhole Operations begin 3/19 Ground Anomalies: 072/2110 D16 pass lost due to antenna interlock problem. D27 brought up for replacement support. Lost 41 minutes of CMD ability. Data covered by SSR (38 minutes) and D27 (227 minutes). 072/2245 TM Dropout due to possible RFI at D27. Lost 1 minute 16 seconds of unrecoverable VC0/VC1 data. 073/1115 Late AOS due to a D66 antenna pointing problem. Lost 12 minutes CMD ability, and 10 minutes of TLM recoverable from the SSR. 073/1952 Received 36 minutes of degraded data from D16, cause unknown. Any lost data is unrecoverable. 073/2231 Received 11 minutes of degraded data due to possible RFI at D16. Any lost data is unrecoverable. 073/2355 Late AOS due to a TCP problem at D46. Lost 33 minutes of CMD ability and TLM (recoverable from D16 and SSR). 074/0036 No ranging performed due to D46 unable to maintain lock on RCVR1. Lost 354 minutes of range data, and delayed CMD activities 32 minutes. 074/0108 No-op command failed at D46 due to station desktop problem. Delayed CMD activities 14 minutes. 074/0306 TLM Dropout due to D46 antenna off-pointing. Lost 4 minutes of unrecoverable TLM and 5 minutes of CMD ability. 074/0810 Late AOS due to misconfigured desktop at D66. Lost 20 mins of TLM, recoverable from SSR. 074/1352 Power outage at Goldstone. Lost 292 minutes of TLM; 270 minutes recoverable from SSR, 22 minutes unrecoverable (2111 to 2133). Lost 1112 and 1248 magnetograms due to lack of DSN coverage. Lost 270 minutes CMD ability. 074/1600 TLM Dropout due to D27 station interface problem. Related to previous anomaly and shares same impacts. 074/2023 D16 unable to support pass due to transmitter problems. Related to previous D27 anomalies and shares same impacts. 074/2257 POCC unable to uplink time-tagged command load due to "load open error." Exact POCC problem TBD. New load generated and uplinked successfully. 075/0438 TLM Dropout due to TLP failure at D34. Lost 2 minutes of unrecoverable TLM.
