* Telemetry Keyhole (SOHO will stay in TM Submode 5 during the Keyhole): 2005/06/05 - 2005/06/25: 26 m 2005/06/09 - 2005/06/20: 34 m * 2005/05/05: End of MEDOC Campaign. * Mercury entered the C2 FOV from the right on 2005/06/02 @ 00:32 UT. * 2005/05/30 - 2005/06/03 between 06:00 - 09:00 UT: C2 Plumes Study: "Microflares, Jets and Macrospicules in and Around PCH". During this time: C2 orange/clear subfield images at a 5 min cadence. FOV 14x16 LOCS block region over the South Pole. --> No LASCO CME watch during the time of the run. * 2005/05/28 - 2005/06/05: LASCO Extra PBs for 3D CME Study. During this time (for the CME watch): - only 1 C2 Orange/Clear per hour; - only 1 C3 Clear/Clear per hour; and - No EIT CME Watch (only synoptic: 4 EIT 195 per day). * Medoc Campaign started on May 16. Since then SOHO is in Telemetry submode 5.
W Limb Slow development of a system of faint loops since late on previous day. 00:32 UT E Limb Bright ragged front already half way to the end of the C2 FOV. GOES recorded a C7.2 X-ray flare late on previous day from NOAA AR 10772 (S17E38), between 22:03 - 22:25 UT with peak emission at 22:18 UT. 02:32 UT E Limb Small front just appearing. It develops as a bright ragged front by 03:32 UT. 06:00 - 09:00 UT C2 Plumes study. NO LASCO CME watch images. (see on top "Points of Interest"). 13:32 UT E Limb Another bright ragged front. Extremely faint extensions can be guessed to S. GOES reportes a B8.7 X-ray flare on NOAA AR 10772 (S17E31) between 12:01 - 12:23 UT with peak emission at 12:10 UT. 18:32 UT W Limb Faint and diffuse loop front superposed in the LOS with the slow development of a system of faint loops. Difficult to give an exact time of first appearance. It was first seen in C3 at 20:38 UT, developing slightly toward WSW. 19:32 UT ES East Diffuse and ragged front. It fades relatively close to the inner edge of C3.
01:32 UT ES East Very elongated loop-like front. It fades throughout C3. 04:32 UT ES East Diffuse loop-like brightening (some signatures already in previous frame, by 03:32 UT). Inpection of the C2 Orange/-60 deg sequence shows the diffuse front first appearing at 04:09 UT, followed by a brighter ragged loop front at 05:09 UT (though by 04:49 UT some brightening can already be seen). In this sequence, this loop front appears much brighter above the E limb. Signatures of the event are gone after the data gap. GOES reported on NOAA AR 10772 the following events: - a C3.1 X-ray flare (S17E21) between 01:53 - 02:38 UT with peak emission at 02:24 UT, and - an M1.3 X-ray flare (S17E22) between 04:03 - 04:16 UT with peak emission at 04:11 UT. 06:00 - 09:00 UT C2 Plumes study. NO LASCO CME watch images. (see on top "Points of Interest"). 10:49 UT EN East (Time of C2 Orange/-60 deg): Faint and diffuse ragged loop front. The front is completely surpassed by a very bright and big loop front by 12:49 UT (time at which this big loop front is first seen, its LE being already at the end of the C2 FOV). Time of the last C2 image analyzed: 13:32 UT.
