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.
ES East The slow development of the system of loop fronts continues. It is followed by a big twisted structure. WIDTH in C3 at 16:18 UT: ~ 60 deg. 00:30 UT WN West Elongated loop front. 01:54 UT N Pole Jet-like front.
