Points Of Interest

- 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).

- 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 at 20:00 UT closing doors. LASCO will open and resume ops 
Thursday March 24 15:00 UT.

- 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).

- Venus entered the C3 FOV from the right on 2005/02/26

	00:48 - 11:36 UT	Temporary DSN Data Gap.

	  W Limb	Gusty outflow after the data gap all along the rest
			of the day. 

17:48 UT  S East	Very faint ragged loop front in the gusty outflow that 
			followed the 3-part structure CME event on previous 
			day. Barely visible in C3. 

2005/03/17 (Thursday)

00:48 UT  W Limb	Ragged and diffuse front preceded by a couple of not-
			well-defined fronts late on previous day. They all
			fade close to the inner edge of C3. By the time, the 
			slow development of a system of loops can be seen
			superposed in the LOS.

07:12 UT  W Limb	Ragged front.

	07:36 - 13:36 UT	Temporary DSN Data Gap.
