Occasional C-class flares are possible from region 8040, selected for SUMER AR and Sunspot studies today. Stable filament continues to appear at North-East limb.. Check yesterday's EIT 304 image at 19:18 UT for some beautiful solar activity. GBO STATUS (JOP 9): ------------------- Supports from THEMIS and PIC-DU-MDI. INSTRUMENT STATUS : ------------------- CDS: Nominal. (See Below for plan) SUMER: Nominal. No possibility to analyze first results because of planning meeting in the morning (See Below for plan) EIT: Nominal. Performing shutterless mode today. Will not be able to UVCS: Nominal. Continuing collaboration with Ulysses. Pb intensities PA 80 (3.5 and 4.5 Rs) LASCO: Nominal. Continuing synoptic and plume study in the north (FeX) possible jet study in C3 at the south pole. MDI: Nominal. Running dynamics until June 13. Dopplergrams every 30 seconds in the campaign that follows (after June 13). JOP 9 : - Target selected for JOP 09 : North-East filament Pointing: (-755, 566), position angle 52 degrees, 36N, E73, for May 24; same pointing corrected for solar rotation for May 25 & 26. May 24 PLANNING: CDS : - Synoptic observations (00 - 07 UT) - JOP 9 (07 - 12 UT) - Study of height of the transition region on North Pole. 6 (4'x4') rasters are performed starting from (530, +830), covering the polar hole from West to East (12 - 24 UT) SUMER : - AR filament study; approximate coordinates (628, -276), solar rotation taken into account, pointing optimized if needed (01 - 07 UT) -(JOP 9) filament search (07 - 12 UT) - Transition region observation 14'' over the limb in Lyman alpha, pointing within the CDS FOV in the first two hours ( 12 - 22 UT) - Bright Point Study ( 22 - 24 UT) EIT: - AR joint observation May 25 PLANNING: CDS : - Synoptic observations (00 - 07 UT) - JOP 9 (07 - 12 UT) - Engineering activities (12 - 14 UT) - Supporting the observational program of SUMER devoted to Oscillations in Transition Region at high time resolution (14 - 24 UT) SUMER : -continuation of BP study (00 - 07 UT) -(JOP 9) TBD (07 - 12 UT) - Oscillations and Network study in Coronal Hole; pointing accounting for solar rotation (650, 740) to be optimized ( 12 - 24 UT) May 26 PLANNING: CDS : - Synoptic observations (00 - 07 UT) - JOP 9 (07 - 12 UT) -Coronal Hole Macrospicule study at South Pole pointing x=0, 20 '' outside the limb (12 - 24 UT) SUMER : -Continuation of Oscillations and Network study in Coronal Hole; (00 - 07 UT) -(JOP 9) TBD (07 - 12 UT) - Coronal Hole study continues (Lyman beta), BP in CH (12 - 24 UT) coordinates x,y -- (650, Y - to be determined) May 27 PLANNING: CDS : - Synoptic observations (00 - 06:30 UT) - JOP 12/17 filament and AR studies, pointing to be decided during the weekly meeting (06:30 - 12 UT) - JOP 33 (12 - 16 UT) - support to oscillation program run by SUMER (16 - 24 UT) SUMER : -Continuation of Coronal Hole study, BP (Ne VIII) (00 - 06:30 UT) - JOP 12/17 : TBD (06:30 - 12 UT) - JOP 33 : TBD (12 - 16 UT) - Oscillations program proposed by K.Muglach and B.Fleck, pointing (650, 0) (16 - 24 UT) This planning completes the first week of operation from MEDOC.
