00:54 UT SS East Faint jet-like front that quickly fades. 01:31 UT S West Small brightening just appearing to S of event reported to start at 23:30 UT, develops as a ragged and expanding loop front [1]. It is followed by a structured core (its inner front first seen in C2 at 02:54 UT) [2]. By 03:30 UT, a system of faint and expanding loop fronts start to ve visible above the S Pole [3]. By 06:54 UT this system of loops spans ~ 145 deg (from PA 110 - 255). Feature [1] is first seen in C3 appearing above the SW Limb at 03:18 UT. Feature [2] follows behind at 04:42 UT. Finally, Feature [3] appears above the S Pole at 05:42 UT, partly superposed in the LOS with [2]. The mean plane- of-sky speed of the different features involved is as follows (based on C3 data): Feature [1] at PA 226: 520 km/sec (no acceleration) Feature [2] at PA 225: 400 km/sec (no acceleration) Feature [3] at PA 187: 300 km/sec (no acceleration). The last measurement is not that reliable due to the faintness of its LE (and superposition with Feature [2]. GOES reported no significant X-ray activity by the time prior to the LASCO C2 event, though it recorded a B3.7 X-ray flare on NOAA AR 10876 (S17W41) between 03:28 - 05:00 UT with peak emission at 04:35 UT. EIT 195 images shows between ~ 00:24 - 01:36 UT the eruption of the rest of the filament (see entry at 22:30 UT on previous day), between AR 10876 and E05. It is visible at least as far as skirt of the South Polar Coronal Hole at ~ S60. EIT shows then, between ~ 01:13 - 06:48 UT, the slow evolution of post-CME loops to SE of AR 10876. Given the observational characteristics of the event C2 and C3 the event has therefore been catalogued as a Partial Halo Event, frontsided, associated to a filament eruption. 07:54 UT N West Faint and elongated front starts to be discernible. 15:06 UT S West Diffuse front preceding the development of a bright and elongated ragged loop front. A bright ragged loop front follows at 15:30 UT a little bit to N developing toward WNW. It is followed by the slow development of a system of faint loop fronts on W. EIT 195 images show signatures of a narrow backsided CME between ~ 14:24 - 17:36 UT. 18:30 UT ES East Extremely faint and diffuse front that quickly fades. GOES recorded a C1.1 X-ray flare on S10E90 between 17:34 - 18:15 UT with peak emission at 17:45 UT.
02:30 UT W Limb A small front develops superposed in the LOS with the trail of the slow system of faint loop fronts reported on entry at 15:06 UT on previous day. Last C2 image available by the time of writing: 12:30 UT
