KEYHOLE Operations:
------------------
Mon 02/04 - Sun 03/02: 26 m keyhole
Mon 02/11 - Sun 02/24: 34 m keyhole
- EIT CCD Bakeout scheduled for 02/22 ~ 21:00 UT thru 02/28 ~ 22:00 UT.
- S/C Maneuvers (SK, MM, and Roll) on 02/22. EIT observed the Roll.
- UPDATED: LASCO safed for S/C Maneuvers on 02/19 ~ 13:30 UT and
recovered on 02/23 ~ 20:00 UT. After recovering, LASCO will operate
in improved cadence (SM5): C2 --> 12 min cadence, C3 --> 30 min cadence;
in effect until 02/29.
- During telemetry outage periods for this Keyhole LASCO and EIT will
not be recorded (and instruments will remain idle).
