LASCO Activity Report for
August 11, 2008 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
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 planned for: 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 22:00 UT
LASCO recovery: 2008/08/21 19:00 UT (still TBC)
EIT will observe during SOHO maneuvers on 08/21 in Sub Mode 5
- 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.
