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: 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 21:30 UT . LASCO recovery: 2008/08/22 17:30 UT . EIT will observe in Half Res during SOHO maneuvers on 08/21 in Sub Mode 5 at 10 min cadence. - 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.
12:00 UT E Limb Apparently twisted structure starts to be discernible developing gradually. Difficult to give an exact time of first appearance. Pseudo- continuous flow superposed in the LOS, moving apparently faster. WIDTH of the Event in C3 at 23:18 UT: ~ 40 deg.
00:24 - 06:48 UT LASCO Data Gap (C2 time). Last C2 image available by the time of writing: 10:12 UT
