SOHO Daily Meeting Minutes for 1 Dec. 1998 Presiding: J. Hollis (SOC) Notes: K. Schenk (EIT) FOT REPORT ----------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: MDI Continuous (332/1525 - 337/0730) TR Maintenance including record session Planned Activities: CEPAC S/W Upload,ACU/CDMU Memory Dumps,RSL,VIRGO Upcoming Operations: 12/21/98 Momentum Management and Station Keeping (1 Min burn, 130 g fuel) Ground Anomalies: 334/1805 4 Min Lost Commanding. D24 Lost command frames during transmission. 335/0730 9 Min Late AOS. D61. Difficulty acquiring 1-way downlink 335/0744 5 Min commanding delay. D61. CPA problem SPACE WEATHER ------------- SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. C-CLASS ACTIVITY IS EXPECTED AND MODERATE ACTIVITY IS POSSIBLE IN A NUMBER OF SUNSPOT GROUPS. REGIONS 8395, 8396, AND 8397 ARE EXPECTED TO BE THE PRIMARY FLARE PRODUCERS. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY QUIET TO UNSETTLED WITH THE POSSIBILITY OF ISOLATED ACTIVE PERIODS. Jet out of NE comes from AR 8395; inverted cusp outflow from SE limb. Lots of small brief outbursts from AR 8395, 8397 LASCO sees defined jet streamer from the NNE. C2 sees a CME from East limb starting at 09:15 UT, later seen in C3. MDI sees dark spot growing in high res field. This is an area of possible flare activity; and are observing the emerging flux from this region. Instrument Reports ------------------ EIT Nominal. CME Watch at 12 min cadence 195A LASCO Nominal. C2 and C3 synotics for CME events C1 FP door closed program 2-hour cadence in FeXIV/clear Begins Ulysses/UVCS support in C2 orange/clear Pb seq. UVCS Nominal. Began Ulysses densities program support. Will start He I Focusing Cone program and synoptics later. SUMER Powered-Off CDS Nominal. High Cadence study with MDI east of AR 8395 on emerging flux region for 8 hours. Then NIS/GIS engineering calibrations. Tonight: synoptics then gravitational focusing cone program. MDI Nominal. Running 3 variable high res campaign today in top half on high res field. Observing the emerging flux of this area. GOLF Nominal. Continuous observations and engineering. Scans of detectors and analyze spectra to determine detector aging. TRACE Not present.
