SOLAR STATUS ------------ - Not much activity predicted for the active regions moving across the disk. - LASCO and UVCS saw slow CME on the East limb early yesterday. LASCO reports that the CME is still in progress. INSTRUMENT STATUS ----------------- CDS: Nominal. East limb study. Synoptic. 30 hour observation stepping inward toward sun from the East. SUMER: Door closed UVCS: Nominal. Global Sun Study: South Pole @ 1.5 - 3.6 Solar Radii Tonight will skip synoptic observation, and afterward observe the North polar coronal hole LASCO: Nominal. Christmas movie campaign still running and will continue until end of high rate on Friday. EIT: Nominal. MDI: Nominal. Full disk and high resolution magnetograms A.O.B. ------ Weekly meeting on Friday: Instrumenters may want to take care of all planning issues before the holiday tomorrow (Happy New Year!). MDI would like to do collaborative magnetic field studies Tuesday through Thursday with anyone interested before going into continuous contact.
