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 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.
LASCO Doors closed until ~ 16:00 UT (because of S/C Maneuvers on 08/21). First C2 image after recovery: 16:40 UT First C3 image after recovery: 17:18 UT 21:30 UT WS West Faint spray-like front.
19:30 UT N West Bright fan-like front.
21:30 UT SS West Jet-like front that quickly fades.
00:00 - 06:06 UT LASCO Data Gap (C2 time). 06:30 UT N West Smal blob already under development after data gap. 08:06 UT W Limb Blob-like front starts to be discernible. Last C2 image available by the time of writing: 10:06 UT.
