Points Of Interest

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: 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.

12:00 UT  E Limb	Apparently twisted structure starts to be
			discernible developing gradually. Difficult to
			give an exact time of first appearance. Pseudo-
			continuous flow superposed in the LOS, moving
			apparently faster. WIDTH of the Event in C3 at
