SOHO Daily Meeting Minutes for 1 September 1999 Chaired by: L. Roberts (S0C) Notes: K. Schenk (EIT) DOY: 244 FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: VIRGO, RSL New tracking star (mag 6.45, slot 1), TM Subformat swap (5 to 6) Planned Activities: VIRGO Extra VC2 (1630-1930) Upcoming Operations: 9/2 - Extra VC2 (1200-1300) 9/3 - Extra VC2 (1430-1630) Ground Anomalies: 243/1352 - TM Dropout; Madrid big pipe outage (3 mins, recoverable) 243/1744 - D61 unable to reacquire TM after noncoho cmd (SSR in record) SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY SHOULD BE LOW TO MODERATE FOR THE NEXT THREE DAYS. REGIONS 8681 AND 8674 REMAIN CAPABLE OF PRODUCING ISOLATED M-CLASS EVENTS BUT THAT CAPABILITY IS EXPECTED TO DECREASE AS DECAY IN THESE REGIONS CONTINUES. THE POSSIBILITY OF A DECAY PHASE MAJOR FLARE FROM REGION 8674 REMAINS. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD SHOULD BE PREDOMINANTLY QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED ACTIVE CONDITIONS ARE POSSIBLE DURING THAT TIME DUE TO OBLIQUE IMPACTS FROM RECENT CMES THAT WERE NOT DIRECTLY AIMED AT THE EARTH. THERE IS A SLIGHT POSSIBILITY OF A SOLAR PROTON EVENT FROM REGION 8674 DURING THE PERIOD. 8/31 DOY 243 - 9/01 DOY 244 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form19990901.html LASCO 8/30: Data gap during estimated CME due to C3 flare/CME with wave in EIT at 00:24. Will recover data and analyze results later. INSTRUMENT STATUS ----------------- CDS: Nominal. JOP 76 today. Tomorrow GIS engineering SUMER: Nominal. Door closed, not observing. UVCS: Nominal. Continued Synoptics and JOP 76 LASCO: Nominal. C2 and C3 synoptics while CME watching. C2 pB campaign for whole sun month JOP 76 EIT: Nominal. 195A CME Watch in full res. JOP 76 MDI: Nominal. Full disk mags and cropped dopplergrams. Monthly Cals tomorrow. TRACE: Nominal. Active Region campaign, and Streamers in JOP 76 AOB --- Reminder from yesterday, Comet contest announced and managed by Doug Biesecker. From now till Sept 15, 1999 entries will be accepted to guess the date and time of the perihelion of the 100th comet discovered by SOHO/LASCO data. Prize award will be lunch at resaurant of choice.
