ISOLATED CLASS C FLARES ARE EXPECTED, PRIMARILY FROM REGION 8232. THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT UNSETTLED TO ACTIVE LEVELS. At this time there are 8 active regions visible on disk. Saturday flare from AR 8232 at 14:50 UT; C3 class. Microflares and brightspots seen in EIT throughout the day. Sunday CME from AR 8230 at 23:00 UT Today CME from the NW limb at 06:30 UT Targets for today; JOP070: disk center, quiet sun (MDI high res field) JOP009: Observing fillament in SSE area INSTRUMENT STATUS ----------------- TRACE: Nominal. Over the weekend continued the 14 day Active Region campaign with completion at noon tomorrow. CDS Nominal. AR studies over the weekend on the west limb. Saturday ran 3D Active Region Campaign and AR Monitoring program as well as Limb studies. Today AR Monitoring and JOP070. UVCS Nominal. Over the weekend streamer study in NW. Today Starting Interplanetary He I program with mirror scaling at 7 & 9 Rsun positions. LASCO Nominal. Over the weekend synoptics and weekly dark calibrations. Tomorrow starts the UVCS/LASCO Streamer study in C1. EIT Nominal. Weekend CME Watch. Today JOP070 from 15:00-19:00 in 195A at minute cadence 7x7 subfield through the week with the CME Watch. MDI Nominal. Weekend AR studies in 3 variables using the 'extract' program with full disk images. Sunday full disk images with 2 variables. Today MDI Flare Watch program in 75% of disk for velocity studies and calibrations. SUMER Nominal, Weekend detector turned off. Today detector turned on at 13:20 UT. Lymon-Alpha Full Sun Profile program off-limb coords. AOB: SUMER June 8-9 planning details from MEDOC: --- 8 June 13:30 UT Detector B on 15:00 UT Start of JOP070, x= 0. , y= 0. lines used: Si IV and O IV 21:00 UT H I Lyman Alpha full Sun profile using the telescope scattered light at x= 0., y = +/- 1700. 9 June 06:00 UT JOP09, pointing x = -380., y = -796. Slope of the Lyman continuum in a filament. 08:00 UT JOP09, pointing x = -380., y = -675. Filament in Ne VIII, O IV and N IV lines For cooperating instruments, from 6:00 UT to 13:00 UT the center of field-of-view is -380., -796. 15:00 UT Start of JOP070, x= 0. , y= 0. lines used: Si IV and O IV
