SOHO Daily Meeting Minutes for Thursday 12 December 2002 ANNOUNCEMENTS ------------- * Many schedule changes are taking place this week due to TDRS spacecraft. The DSN and NRT schedule are changing faster than we can keep up with them, so the web spacecraft schedule won't always be updated. Call the SOCs for the latest information if you need it. * Current RHESSI default target is AR 10220 * The Voice Distribution System (VDS) will undergo maintenance on Saturday December 14 from 8am - 3pm. This downtime will be used to replace the system's 48 VDC power supplies. During this downtime VDS users on site at GSFC will not be able to signal Voice Control, use Dial Intercom, and VDL Hotlines. All other VDS operations will not be affected. * SOHO potluck party is Tuesday, 17 December at 11:30 am, sign up in EOF or FOT office soon. * Commanding times for next week: Monday - D27 until 18:30 UT then possibly D46. Tuesday - Gap from 14:30-18:30 UT then D46. Wednesday - D16 all day. Thursday - D27 all day. Friday - Demo test in the morning, D46 starts at 18:30 UT. Saturday - Gap from 17-18:30 UT. Sunday - Gap from 13-19 UT. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: VIRGO Planned Activities: VIRGO, Nominal HGA Table Upcoming Operations: None Ground Anomalies: 345/2011 SH4WS2 and SH4XT1 hung, cause unknown. Operations failed over to String 5 until String 4 operational again. 345/2213 Received degraded TLM from 2213 until 2240. Lost data is unrecoverable. Bad data impacted ability to command, delaying pass activities, and possibly impacting 2224 magnetogram. 346/0630 Command outage from 0630 until 0718 due to a CPA failure at D66. Lost 40 minutes of range data. Delayed pass activities 48 minutes. Lost TLM from 0703 until 0708; data is unrecoverable.
