Now rotating around limb. Sunspot near central meridian. Eruption of SW prominence with ejection lifted off at 01:00 UT. INSTRUMENT STATUS ----------------- CDS: Nominal. Yesterday: loop study, obs of AR in South, intercal001, quiet sun movies. Today: loop study, obs of AR in South, JOP 73 at 17:30 UT. Tomorrow: put in GIS study of active region and support waves study. SUMER: Nominal. Yesterday: quiet sun network study and intercal001. Observed AR 8113 with vertical slit ~.5R, leading edge loop study. Today: Continue Quiet sun network study, and participation in Blinkers. UVCS: Nominal. Yesterday: ICAL001. Today: 3 hours of continued He I focusing cone observations. 6 hours of Spectral study above AR 8113 ~1.5R. LASCO: Nominal. Yesterday: Synoptic program, West limb AR observations and North polar plume study. Tests taken that include AR 8113 to run green line C1 scans in FeXIV filter for doppler velocities. Today: Synoptic observations, and Green line program in C1. EIT: Nominal. Yesterday: Loop study and intercal001. Today: CDS/EIT loop study from 8:00-9:00 UT with subfield in a 2.5 min cadence. JOP 73 Blinkers from 17:30-19:00 with a 3 min cadence. MDI: Nominal. Yesterday: network study in lower half of high resolution field of view with a delayed start due to station problems. Today: blinker studies with CDS, SUMER, and EIT in the bottom half of high resolution field of view.
