00:54 UT W Limb Faint loop front that quickly fades. 01:54 UT S West Slow development of a system of faint loops. 09:30 UT W Limb Diffuse jet-like front developing slightly toward WSW. It fades throughout C2. 10:30 UT SS West Diffuse front. Please note that it is difficult to give an exact time of first appearance due to the diffuseness of the front. The event later develops as a system of wide loop fronts clearly discerned since 12:54 UT. By 18:06 UT, when the front reached the outer edge of C2, the event already extended over the S Pole. The event is first seen in C3 above the SW Limb at 16:42 UT. Several fronts can be discerned developing afterward. In particular one that is first seen above the S Pole at 19:42 UT. By 00:18 UT on next day the whole event spans ~ 130 deg from PA ~ 140 - 270. By ~ 05:42 UT (on next day) the event is practically no longer visible, apparently without having reached the end of C3 FOV (~ 23 solar radii at PA ~ 210). The mean plane-of-sky\ speed for the LE of the outermost loop front at PA ~ 207 was ~ 245 km/sec (based only on C3 data) showing a slight acceleration. This event apparently disturbs the evolution of the event reported to start at 01:54 UT, as inferred from C2 images. However, it is not seen to be surpassed by our event (C3). EIT Fe XII images show signatures of a CME event (filament lift-off) between 11:00 - 15:24 UT nearby NOAA AR 10664 (mainly to the SE of it). The ejection is seen to develop toward SW. On the other hand, GOES did not record any significant X-ray activity by the time that could be associated to the event. The event has therefore been determined as a 'partial' halo CME, frontsided. 13:31 UT N West Faint spray-like front preceding a ragged loop front at 16:30 UT. 18:30 UT W Limb Small ragged front that fades throughout C2. 20:58 UT E Limb Very faint expanding loop front becomes discernible. Another one develops within. The latter apparently surpasses the first one close to the inner edge of C3. Difficult to give an exact time of first appearance.
01:54 UT S East Extremely narrow and elongated expanding loop front at the PA of the southern leg of event reported to start at 20:58 UT on previous day. 09:06 UT W Limb Bright loop front, cavity and twisted inner core.
