LASCO Activity Report for
March 22, 2005 SOHO Science Daily Meeting

Planner: K. Schenk, G. Stenborg

Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.


Points Of Interest

- Upcoming Maneuvers: The S/C roll back to 0 degrees is set for March 22.  
LASCO will be safing for the roll, and station keep maneuvers Monday 
March 21 (by the end of the day) closing doors. LASCO will open and resume 
ops late on March 23 (Wednesday).

- During the keyhole LASCO will image at an improved cadence of C2 @ 12
minutes and C3 @30 minute cadences. This includes daily orange filter pB
sequence and flat field orange/blue images. Using the keyhole recording
scheme most all LASCO data will be recovered.

- EIT CCD Bakeout: 2005/03/11 (Friday) - 2005/03/31 (Thursday).

- On 2005/03/11 @ 15:00 UT (Friday) SOHO changed to Submode 5. 
 
- 34 m Telemetry Keyhole began on 2005/03/10 (until 03/24).
- 26 m Telemetry Keyhole began on 2005/03/02 (until 04/01).

- Venus entered the C3 FOV from the right on 2005/02/26 
  (by the end of the day).
