Points Of Interest

- Venus entered the C2 FOV from the right on 2005/03/24 
  (by around 16:00 UT).

- 34 m Telemetry Keyhole began on 2005/03/10 (until 03/24). Finished.
- 26 m Telemetry Keyhole began on 2005/03/02 (until 04/01).

- 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.
