KEYHOLE OPERATIONS: ------------------ . 2008/08/01 - 2008/08/30: 26 m keyhole . 2008/08/08 - 2008/08/22: 34 m keyhole This keyhole will not have any LASCO telemetry outages. There will be long DSN gap periods but all data will go to record and retrieved sooner or later. - LASCO will run in improved cadence during EIT CCD bake (C2 12 min, C3 30 min) period. - EIT CCD Bakeout planned for: 2008/08/08 ~16:30 UT - 2008/08/20 07:00 UT. (pre-bake cals from plan 2008/08/08 15:00 - 16:10 UT) (post-cals from plan 2008/08/20 21:30 - 22:45 UT) - SOHO S/C maneuvers: 2008/08/21 14:00 - 22:00 UT (MM, SK, roll to solar north -0 deg-) LASCO safing: 2008/08/20 22:00 UT LASCO recovery: 2008/08/21 19:00 UT (still TBC) EIT will observe during SOHO maneuvers on 08/21 in Sub Mode 5 - During long DSN gaps EIT will not move the sector wheel and will observe in 195A CME Watch until real-time contacts for synop sets.
EN East Slow development of a system of faint loop fronts since early in the day. Difficult to give an exact time of first appearance. Big twisted structure follows. WIDTH of the Event in C3 at 22:18 UT: ~ 45 deg.
00:00 - 02:36 UT LASCO Data Gap (C2 time). 13:36 UT WS West Faint elongated loop front. 19:12 UT W Limb Ragged loop front, twisted trail. WIDTH in C3 at 03:42 UT (the next day): ~ 30 deg.
00:36 UT W Limb Ragged loop front. WIDTH in C3 at 04:42 UT: ~ 25 deg.
01:12 - 07:00 UT LASCO Data Gap (C2 time). Last C2 image available by the time of writing: 15:36 UT
