KEYHOLE OPERATIONS: ******************* 11/15 - 12/02: 26 m keyhole 11/19 - 11/28: 34 m keyhole * 11/19 11:00 UT - 11/24 11:00 UT: EIT CCD Bakeout (EIT resumed observations on ~ 11/24 @ ~20:00 UT). * 11/24 ~20:00 UT - 11:26 24:00 UT: EIT 171A cme watch in half res (sm5) to support SECCHI program (12 min cadence). * 11/27: S/C Maneuvers (SK and MM) LASCO will close doors and safe for SOHOs maneuvers on 11/26 and EIT will then begin 171A cme watch in full res with a 7 minute cadence thru 11/28 22:00 UT where LASCO recovers. We will stay in 171A thru 11/30 and change into 195 on 12/01. * LASCO will continue with C2 pb orange filter 6 hr cadence, C3 pb orange filter 12 hr cadence while possible during the keyhole period (only during real-time contacts).
EN East Slow development of a system of faint loop fronts since late on previous day. Difficult to give an exact time of first appearance. Twisted (rather circular) structure shows up early on the day. WIDTH in C3 at 12:42 UT: ~ 30 deg. 12:50 - 18:50 UT Temporary LASCO Data Gap (C2 time). 19:26 UT S Pole Diffuse jet-like front. Last C2 image before safing for Maneuvers on 11/27: 22:26 UT Last C3 image before safing for Maneuvers on 11/27: 21:42 UT
