KEYHOLE Operations: Dec 3 - Dec 20 (26 m) Dec 6 - Dec 17 (34 m) EIT CCD bakeout (+ pre and post cal) between Dec 2 ~ 18:12 UT - Dec 18 21:00 UT.
NOTE: ---- Several C- and M-class X-ray flares on NOAA AR 10826 during the day. In particular: - Impulsive C1.7 (S04E17), peak at 00:34 UT - Impulsive C1.3 (S04E17), peak at 02:11 UT - M6.5 (S03E19) between 02:42 - 03:00 UT, peak at 02:52 UT - C4.9 (S02E14) between 05:52 - 06:09 UT, peak at 06:00 UT - M7.8 (S03E14) between 10:05 - 10:25 UT, peak at 10:12 UT - M1.0 (S03E07) between 20:01 - 20:52 UT, peak at 20:30 UT - M2.0 (~S02E08) between 20:57 - 21:37 UT, peak at 21:19 UT Some LASCO events may be associated to some of them. 01:31 UT E Limb Big and bright ragged loop front with trailing material. EIT 195 images show a CME either at or just over the ENE Limb between 00:48 - 02:36 UT. 04:54 UT ES East Elongated and relatively narrow loop front. 07:31 UT ES East Diffuse brightening just appearing develops as a bright loop front (much brighter to S). Faint loop-like extensions to S (not discernible in C3). By 07:54 UT, a ragged and apparently asymmetric loop front develops on the E limb, at a position that seems to match that of the apparent northern leg of the bright loop front. 11:06 UT SS West Very faint and diffuse (wide) loop front, spanning up to almost the W Limb. Apparently not discernible on C3. 11:30 UT N East Elongated (and not-well-defined) loop front along the streamer.It was preceded at 08:06 UT by a similar front, though in this case it is difficult to discern whether it was part of previous event or an independent feature. 15:30 UT ES East Elongated (fan-like) loop front. It fades throughout C3. 16:06 UT E Limb Ragged blob-like front starts to be discerned slightly above the C2 occulting disk.
NOTE: ---- Multiple B- and C-class X-ray activity continues on NOAA AR 10826 (AR close or around the central meridian). 01:24 UT ES East Elongated loop front with faint loop-like extensions to S. It fades throughout C3. System of faint loops starts to develop on E by 02:12 UT, fading then throughout C2. 09:00 UT S East Slow development of a system of faint expanding loop fronts. It fades throughout C3. 16:48 UT W Limb Diffuse brightening precedes the slow development of a system of faint loops. Apparently another structure, twisted, develops by 19:12 UT (though it is difficult to give an exact time of first appearance) superposed in the LOS. It seems to move faster. 20:24 UT ES East Narrow loop front. Very faint expanding loop-like extensions develop to S. They superpose in the LOS with the still evolving slow event reported to start at 09:00 UT.
NOTE: ---- Multiple B-class X-ray activity continues on NOAA AR 10826. 01:24 UT WS West Elongated loop front slightly curved toward S. It fades throughout C3. 11:24 UT S East Very faint loop front with fainter extensions to S. 19:12 UT S East Very faint expanding loop front. It fades throughout C3.
