KEYHOLE Operations: Dec 3 - Dec 20 (26 m) Dec 6 - Dec 17 (34 m) EIT CCD bakeout (+ pre and post cal) between Dec 2 ~ 18:12 UT - Dec 18 21:00 UT.
13:48 UT E Limb Ragged loop front. Very faint in C3. By 14:12 UT, an extremely faint and diffuse front starts to be seen on SE. Difficult to say whether it is associated to the ragged loop front. 17:48 UT E Limb Another ragged loop front. Also faint in C3, fading throughout its FOV. 21:36 UT E Limb Bright ragged loop front with apparently twisted trailing material. It fades throughout C3.
02:12 UT E Limb Apparently circular structure in the trailing material of event reported to start at 21:36 UT on previous day. 21.12 UT N West Extremely faint loop front starts to be discernible above the NW limb. 23:24 UT E Limb Ragged front that fades throughout C3.
05:12 UT S West Kind of reconection event ("pair formation") well above the limb: very faint blob-like front and corresponding infalling material. Difficult to give an exact time of first appearance. 15:36 UT S West Another "pair formation" event. 19:12 UT N East Wide and expanding loop front with faint extensions that extend all above the N Pole up to the W Limb by 19:24 UT. The C2 occulting disk seems to be fully covered by the extension by 19:48 UT. The event is first seen in C3 above the ENE Limb at 20:18 UT with very faint extensions above the N Pole up to the W Limb. By 21:42 UT, the faint extensions make the event appear as a very faint full halo. The bulk of the ejection moves mainly toward ENE. The halo signature fades at the very beginning of next day. GOES reported a B5.5 X-ray flare on NOAA AR 10830 (N15E14) between 18:41 - 19:10 UT with peak emission at 18:52 UT.
No significant activity.
