00:06 UT E Limb Slow (at least at the very beginning) development of a faint loop since late on previous day that later superposes in the LOS with a not-well-defined and diffuse structure. See next event for further details. 06:30 UT E Limb The diffuse structure mentioned in previous event develops as an expanding and aparently twisted big structure apparently affecting the development of previous event. It is difficult to precise the time of first appearance, though by 06:30 UT it starts to be rather well discerned. The mean plane-of-sky speed of its LE was ~ 370 km/sec at PA 108, showing an slight acceleration (based on C3 data). GOES reported a C8.4 X-ray flare on NOAA AR 10794 (S15E28) between 05:25 - 06:22 UT with peak emission at 05:59 UT. EIT 195 images show between 05:48 - 09:00 UT a dimming and wave at least 180 deg in extent toward west. 01:54 UT N West Very elongated and narrow loop front. 10:00 - 11:15 UT ICAL01 (Intercalibration for EIT with CDS). NO LASCO C2/C3 images. 20:30 UT E Limb Extremely faint and diffuse front. 23:30 UT W Limb Slow development of a system of loop. By the beginning of next day, an elongated an apparently twisted structure can be seen.
08:54 UT N East Doupble loop front: one developing toward East, and the other one developing as an asymmetric and expanding loop front toward NE, spanning up to past the N Pole. Some faint and not-well-defined fronts follow to N - NE. GOES reported a long duration C2.8 X-ray flare on NOAA AR 10792 (N15W18) between 06:59 - 08:45 UT with peak emission at 07:59 UT. EIT 195 images show a brightening at 07:13 UT followed by a dimming/wave toward NE. Time of the last C2 image under analysis: 14:06 UT.
