KEYHOLE Operations: Dec 3 - Dec 20 (26 m) Dec 6 - Dec 17 (34 m) Spacecraft Maneuvers on December 15: Station keeping (SK), Momentum Management (MM), and 180 deg Roll. Therefore: - On Wednesday Dec 14, 22:00 UT: Lasco C2 and C3 close doors for maneuver. - On Friday Dec 16, 22:00 UT recover C2 and C3, open doors and resume keyhole observations: C2 @ 12 min cadence, C3 @ 30 min cadence, daily orange/blue filter fieldings, and daily orange filter pB sets. EIT will end bakeout Sunday Dec 18 (started on Dec 02 @ ~ 18:12 UT) from plan at 10:00 UT. The post cal mini set will be taken on the following pass 16:15-22:55 UT. Imaging will resume ~21:00 UT.
N West Gusty outflow along the streamer all along the day. 00:12 UT EN East Slow development of a system of loops preceded by a diffuse and very faint front. It develops as a ballon- type CME, well discerned in C3. 03:00 UT W Limb Faint and small elongated loop-like front. Another one at 04:36 UT. They both apparently fade throughout C2. 16:12 UT S West Bright loop front, preceded by some gusty outflow in the form of small ragged fronts. It superposes in the line of sight (at the beginning) with the slow development of a system of loops. 21:12 UT S East Diffuse and faint small loop front followed by a faint loop front at 21:48 UT.
N West Gusty outflow along the streamer all along the day. 04:00 UT WN West Curved fan-like front. 06:48 UT W Limb Jet-like front, slightly curved toward S. 12:36 UT W Limb Slow development of a loop front with inner core (most likely prominence material). A diffuse brightening (top of the loop) can be seen above the limb since earlier (starting at ~ 12:00 UT). 15:12 UT WN West A very narrow curved loop front (slightly curved toward S) can be seen developing to N of previous event. 15:24 UT WS West Ragged front preceded by a very diffuse and faint front develops to S of event reported to start at 12:36 UT. 19:36 - 24:00 UT Temporary DSN Data gap (C2 time).
00:00 - 08:48 UT Temporary DSN Data gap (C2 time). 08:48 UT S West Elongated loop front along streamer already under development after data gap. Last C2 image available by the time of writing: 10:12 UT.
