Lost I/F between JPL and SPC-40. SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGIONS 8485 AND 8487 MAY PRODUCE ISOLATED M-CLASS FLARES SOMETIME DURING THE PERIOD. GEOPHYSICAL ACTIVITY FORECAST: GEOMAGNETIC FIELD ACTIVITY IS EXPECTED TO CONTINUE AT QUIET TO ACTIVE LEVELS DURING THE FIRST DAY OF THE FORECAST PERIOD, THEN DECLINE TO QUIET TO UNSETTLED LEVELS FOR THE REST OF THE PERIOD. 3/15 DOY 074: 20:12 Filament eruption with disk CME just West of AR8484. C2 and C3 see large CME in SW beginning at 21:35 UT. 3/16 DOY 075: 05:48 Dimming of AR8488. Very nice groupings of Sunspots in Northern Hemisphere. INSTRUMENT STATUS ----------------- CDS: Nominal. Filament study with SUMER, Active Region study with TRACE performed. GIS engineering, Spactra Study with Helen Mason. SUMER: Nominal. JOP095. Filament study this morning. Sunspot studies today then switching to detector B. UVCS: Nominal. Performed synoptics and CMW watch in NNE region. Today, the same. Caught CME in NNE at 07:00 in Oxygen VI. LASCO: Nominal. C2 and C3 synoptics while continuing CME watch. EIT: 195A CME watch. Today the same 195A CME watch with a focusing test using 1.5 degree temperature increase. MDI: Nominal. Cropping (10 pixels from disk removed) disk magnetogram program. TRACE: Nominal. Brightpoints study performed. Kucera Filament study with SUMER and CDS then JOP 83 in 171A and 195A. Will change to Active Region study of 8487 for rest of day with CDS.
