Telemetry Submode change to Submode 6 on 2004/12/28 (Tuesday) at 17:30 UT. - Telemetry Keyhole # 7: 2004/12/13 - 2004/12/29 (intermittent contact). - Spacecraft Maneuvers on 2004/12/21 (Tuesday). Therefore, LASCO was closed for the S/C maneuvers (Station keeping, Momentum management, and 180 deg roll) between Dec. 20 (21:00 UT) - Dec 23 (~ 20:45 UT). - EIT pre-bake cals taken on Saturday 2004/12/11 between 15:24-18:30 UT. The CCD bakeout started at 18:47 UT. The end of the bakeout will be on 2004/12/28 at 10:00 UT. Therefore, no EIT images during that period. - During the Keyhole, LASCO is observing with DSN gap recording availability thanks to the FOT and the SOCs hard work. C2 and C3 observes at a standard synoptic plan of C2 at 10 minute cadence and C3 at the 30 minute cadence with the daily pB and flat field images.
07:12 UT S West Initially bright and very narrow front immediately followed by a faint and diffuse ragged loop front. Similar couple of features follow starting at 08:36 UT. They all fade throughout C3. 14:24 UT W Limb Small front followed by ragged loop-like fronts (on WSW) at 15:12, 17:48, and 21:12 UT, all of them developing toward WSW. After the one at 21:12, the slow development of a faint system of loops can be discerned to S (SW Limb). 23:12 UT S West Ragged front partly superposed in the LOS with the slow development of a system of faint loops.
00:24 UT S West Ragged asymmetric loop front. 01:48 UT S West Another ragged asymmetric loop front. 02:48 UT E Limb Faint and diffuse loop front that fades throughout C3. 03:48 UT WS West Small ragged front. 04:36 UT WS West Not well defined front. This event is most probable associated with the B4.6 X-ray flare reported by GOES on NOAA AR 10712 (S11W71) between 04:17 - 04:28 UT with peak emission at 04:21 UT. 06:36 UT S West Another ragged asymmetric loop front. 09:48 UT S West Bright asymmetric and ragged loop front. 13:12 UT S West Another bright ragged loop front, partly developing toward W. Most of the activity on WSW - SW is most probably associated with the X-ray activity reported by GOES on NOAA AR 10713 - by the time at around S10W70/75 - (several C-class X-ray flares during the last hours).
