KEYHOLE Operations: ------------------- 26 m keyhole: 2007/05/18 - 2007/06/05 34 m keyhole: 2007/05/21 - 2007/06/01 While in Keyhole, improved cadence in LASCO C2 (12 min) and LASCO C3 (30 mins). EIT CCD bakeout ended on 2007/05/24. Observations resumed on 05/25. EIT CCD Bakeout as originally planned: started on 2007/05/18 @ ~15:00 UT and ends on 2007/06/05. Spacecraft Maneuvers on Tuesday 2007/05/29. (Station Keeping, Momentum Management, and 180 deg Roll. LASCO safed on 2007/05/28 @ 12:00 UT and will recover on 2007/05/30 @~ 23:00 UT.
01:36 UT ES East Faint and diffuse jet-like front. 03:48 - 14:00 UT LASCO Data Gap (C2 time). 17:26 - 24:00 UT LASCO Data Gap (C2 time).
00:50 UT ES East Faint fan-like front. 01:26 - 06:06 UT LASCO Data Gap (C2 time). 09:26 - 15:06 UT LASCO Data Gap (C2 time). 15:26 UT E Limb Diffuse front that quickly fades. 15:50 UT WN West Diffuse ragged front that fades throughout C2. 17:26 UT W Limb Bright ragged loop front. Development partly missed in following Data Gap. Twisted structure after Data Gap (LE already past the end of the C2 FOV). WIDTH in C3 at 03:18 UT (on 05/27): ~ 30 deg. 18:26 - 24:00 UT LASCO Data Gap (C2 time).
03:26 - 10:50 UT LASCO Data Gap (C2 time). 11:06 UT WN West Ragged structure already under development after Data Gap. WIDTH in C3 at 14:18 UT: ~ 20 deg. 15:26 - 22:26 UT LASCO Data Gap (C2 time).
01:26 - 04:26 UT LASCO Data Gap (C2 time). Last C2 image: 11:50 UT. Last C3 image: 11:42 UT. LASCO closed doors @ ~ 12:00 UT ahead of S/C Maneuvers on 2007/05/29. EIT will remain open thru the maneuvers at these times: 2007/05/28 12:36 - 17:20 2007/05/29 04:18 - 05:40 2007/05/29 18:00 - 2007/05/30 23:00 EIT is in half res, at a 7 minute cadence.
LASCO Doors Closed because of S/C Maneuvers.
