5 December 1996 SOHO Daily Meeting Minutes Chaired by: L. Allen, C. DeForest Notes: UVCS (R. O'Neal) ANNOUNCEMENTS: The CMS test will occur tomorrow between 8 and 9 am. NRT will be available for backup CMS only. (SUMER sending dummy commands) FOT BRIEFING: DAY: 340 S/C Status: Nominal. S/C Anomaly Summary: 340/0040 DMA failure Accomplished Activities: RSL, VIRGO, CELIAS, SWAN New Guide Star(5.5) Submode 2 Test Planned Activities: RSL, VIRGO, NOM HGA IN Submode 3 until 1700 Extra VC2 21:30-22:30 G/S Anomaly Summary: 339/1404 23 min. TM loss D66 SFG at JPL crashed-data recoverable 339/1916 4 minutes no commanding D46 CPA swap 339/2037 TC Block Length Error D24 Cmds Good w/ Rexmit. 6min. delay BGQ 340/1021 Pocc String Crash D61 338/0600-1000 AOS@0850. Pocc saw large increase in Frame Sequence errors. Slightly Lower Percentages on SSR dump. D66 Pointing directly at Sun. STATE OF SUN: The sun is quiet. EIT 304 image doesn't show any activity. The emerging flux region observed earlier this week seems to have become a submerging flux region. MDI magneto- gram is quiet. LASCO shows development of some streamer structure on the east limb. YOHKOH image is quiet with the south pole hole looking larger than it did in earlier images. INSTRUMENT STATUS: CDS - Nominal. Today: Coronal Hole study (nonpolar). Bright points near disk center. Blinkers study. Tommorow: Focussing cone (JOP 54/55?) SUMER - Nominal. Today: Submode test and Interstellar Helium study. Absorption line study - Lya. Coronal Hole line ratio studies Tommorow: Coronal Hole-outflow velocity study, Polar hole-abundances, temperatures. UVCS - Nominal. Yesterday: Disk observation w/o filter for calibration of detector resolution at 1037 < wavelength < LyB. Synoptic. Today: Interstellar Medium Dust Cone (JOP 56). LASCO - Nominal. Today: Synoptic. Tommorow: Polarization of Color Filter Sequence. EIT - Nominal. Yesterday: Submode 2 test, 195A images every hour. Today: Support Blinkers study. Tommorow: JOP 53. MDI - Nominal. FLat field updated. Being checked at Lockheed prior to upload. AOB: None
