R. Schween presented a LASCO C1 movie of CME activity on Sunday. They therefore contacted UVCS about the activity and UVCS stating observing as well. This large event in the NE also has a bright X-ray counterpart. A prominence had erupted in the south and was followed by the event in the NW an hour later. INSTRUMENT STATUS: CDS: Nominal. Filling Factors on the Active Region to the east. JOP021 and Solar Abundance (Quiet Sun) study. SUMER: Nominal. Network Evolution at disk center and JOP021: Solar Abundances (Quiet Sun) MDI: Nominal. Full-field HiRes Magnetograms every minute for JOP021 same program tomorrow for Blinkers study. EIT: Nominal. Again, saw 3 eruptive events over the weekend. today and tomorrow: 304 sequence CME Watch LASCO: Nominal. CME: even with 30 min images, only 1 frame was significant due to the speed of these eruptive events. UVCS: Nominal. Sat. JOP021 (west limb), Sun. JOP021 (east limb) 1.5-1.6 Solar Radii. Today: limb study in S. Coronal Hole 1.9-2.1 Solar Radii Tomorrow: white light study
