Solar Status ------------ DOY 149: ~02:00 UT CME from behind SW limb 03:24 UT M1 flare in AR in SE, CME. 08:48 UT NW limb, prominence eruption 16:25 UT C-flare, AR 8554 20:12 UT C-flare AR 8554, CME, possible promince eruption, long loops appear. DOY 150: 03:12 UT NE limb, CME, nice post-CME loops 10:24 UT SW limb, CME large spatial extent 12:48 UT NNW limb, prominence eruption INSTRUMENT STATUS ----------------- CDS: Nominal. Jop 103 for 10 hours/day. Oscillation study yesterday then sunpost studies. Tomorrow run Jop103 then prominence observations. SUMER: Nominal. 31 May adjusted slit and wavelengths, Ran Jop 103 31 May, 1 Jun. Macrospicule observations had limited success and will re-run. Off limb Ne VI study for today. Tomorrow run calibration sequence, macrospicules, etc. UVCS: Nominal. Observations for Ulysses - solar wind variability. LASCO: Nominal. During EIT bakeout ran 10 minute cadence C2, and 30 minute cadence C3. Back to standard C2, C3 synoptic. EIT: Nominal. Bakeout from 30-May 13:30 -> 01 Jun 08:00. Calibrations today, then 195 2x2 binned CME watch. MDI: Nominal. High resolution studies, magnetogram+velocity. TRACE: Nominal. La Palma observations followed by AR 8558. Upcoming Observations: ICAL 001 - June 3, 19:30.
