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
