Schenk (EIT) DOY: 019 ANNOUNCEMENTS ------------- * AOB: Another room change for today's SOHO Science Club: Building 21, Room 242. * QUICKLOOKS for today's gaps of 03:26-04:02 UT and 05:24-06:44 UT have been delayed due to IDDS software problems. * SOHO-96 Kreutz sungrazing comet discovered by Doug Biesecker in the Lasco C3 data yesterday. Look at http://sungrazer.nascom.nasa.gov * On February 3 or 4 a Sun-Earth Connection Educational Form group will be in the EOF right after lunch. There will probably be 20 to 25 people. If this creates too much of a problem for anyone, please let the SOCs know as soon as possible. * Snow plan for GSFC/Greenbelt can be found at: http://internal.gsfc.nasa.gov OR http://gsfc-aphrodite.gsfc.nasa.gov/220/snow/snowplan.htm GSFC employee information line (301-286-NEWS) will post messages within 15 minutes of the Center's official decision on status. FOT REPORT ---------- Spacecraft Status: Nominal-Guide Star Swap Spacecraft Anomalies: 019/1143 Automatic On-board Guide Star Swap. Accomplished Activities: RSL,Virgo,Swan Planned Activities: Virgo, Guide Star Swap Recovery Upcoming Operations: 2/1 TR Maintenance Ground Anomalies: 018/1929 2 Minutes degraded TM. D16. Autotrack problems causing low AGCs. 019/0225 21 Minutes Late AOS. D46. Antenna Red. 019/0332 61 Minutes TM lost. D46. Big Pipe Outage. Realtime and VC4 is recoverable. SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGIONS 8824 AND 8831 HAVE THE BEST POTENTIAL TO PRODUCE AN ISOLATED M-CLASS EVENT. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET DURING THE FIRST PART OF THE PERIOD THEN BECOME QUIET TO UNSETTLED. THERE IS A POSSIBILITY OF A SOLAR PROTON EVENT AT GEOSYNCHRONOUS ORBIT DUE TO THE CHARACTERISTICS OF THE M3 X-RAY EVENT MENTIONED ABOVE. 01/18 DOY 018 - 01/19 DOY 019 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20000119.html 01/18 DOY 018 - Lasco C2 reports: 08:54 UT, large CME off West limb with bright front. At 10:06 UT a second event starts with large CME event in West due to the M1 flare behind limb at 09:36 UT. Later, at 17:54 UT a full 360 degree HALO CME event due to M4 flare of AR8831 a near disk center was seen. 01/19 DOY 019 - Lasco C2 reports: 02:54 UT Small wide jetlike CME in SSW near SPole. INSTRUMENT STATUS ----------------- CDS: Nominal. Flare Genesis today, Later ICAL001. Tomorrow Flare Genesis and CME watch with UVCS. UVCS: Nominal. CME Watch campaign at Position angle 255 degrees with synoptics. LASCO: Nominal. Observations with C2 and C3 while CME watching. EIT: Nominal. Full res 195A images at 12 minute cadence. ICAL001 20:30-22:00 UT with CDS MDI: Nominal. Full disk Magnetograms, Intensitygrams and Dopplergrams. One hour High res field today for Sunspots Campaign. TRACE: Nominal. Support Flare Genesis. FLARE GENESIS STATUS -------------------- Flare Genesis confirmed yesterday that they switched to AR 8831. No new email today so instruments will continue with that target.
