A total of 3 C class events were recorded yesterday. Giant sunspot 978 is crackling with C-class solar flares, unleashing three in the past 24 hours. Further C class flares are possible. Flares: C4.5/1F at 10:03, C1.0 at 14:06 and C1.7 at 22:00 UTC. GOES X-ray flux: There was another short duration C class event at ~0830 UTC today. CMEs reported for past two days: December 11-13: No obvious fully or partly Earth directed CMEs were observed in LASCO imagery.

SOT: - MEETINGS -------- We reviewed three CAPs: 1051 for turning off the EPHIN G HV (tobe revised and reviewed again Monday), 1050 for changing the K constant for EPHIN G, to be called by 1051 (Approved), 1052 for backing out the K constant change (Approved).

Side A current also dropped a bit below its normal value of 1.4 A. From last night's 10:35 pm ACIS SOT shift report: "This event appears similar to the two previous autonomous power downs of side A of the DPA presumably caused by a spurious command from the SIM RCTU. The first observation out of the belts OBSID 9777 was executed with only 2 of the 5 requested CCDs on since 3 of the requested CCDs were to be powered by side B of the DPA. OBSID 9777 will most likely have to be redone. The plan is to execute a recovery at the 347:0245 pass before the next science observation (OBSID 9233) begins. The recovery plan includes stopping the current science run, powering on side B of the DPA, and warm booting the BEP to restore version 31 of the flight SW." A real-time procedure was successfully executed at 9:45pm on Dec 13 to restart the DPA Side-B and warm boot the ACIS Back End Processor. An observation of AEGIS-1 was impacted by the event.
