01:31 UT S Pole An initially bright front is seen rising on the S Pole in C2, with fainter loop-like extensions above the SW Limb, and followed by much outflow on the S Limb. Later, by 05:30 UT, a ragged loop front can be discerned in the trailing material. C3 shows the development of the event as, apparently, two superposed ragged loop-like structures, one moving mainly toward S and the other slightly toward NW. Globally, the event spans in C3 ~ 100 deg at 07:42 UT, from PA ~ 140 - 240. The mean plane-of-sky speed was around 500 km/sec, as measured at PA ~ 180 and based on C3 data. GOES recorded a M9.1 X-ray flare on NOAA AR 0652 (N03E13) between 00:14 - 00:43 UT with peak emission at 00:32 UT. EIT Fe XII running difference images record a strong brightening on AR 0652 starting at 00:24 UT and peaking at 00:36 UT. Another brightening occurs at 04:00 UT. 07:31 UT S Pole Complex Event: Basically, at 07:31 UT a bright narrow feature appears above the S Pole in C2, preceding the development of an asymmetric loop front at the S Pole with faint loop-like extensions above the SW Limb. By that time, an extremely faint and diffuse arcade-like front can be discerned in C2 developing mainly toward NE, jointly with another similar one toward NW. Their faintness makes it difficult to establish the exact time of first appearance. On the other hand, C3 shows, starting at 07:42 UT, the development of a faint and diffuse wide loop front on NNE; and starting at 08:42 UT a wide ragged loop front developing on SSW. The former seems to surround later the occultor. The mean plane- of-sky speed was around 913 km/sec, as measured at PA ~ 210; and ~ 652 km/sec as measured at PA ~ 30 (based on C3 data). GOES recorded by the time several C-class X-ray flares on NOAA AR 0652: C1.7 (N05E13) between 06:33 - 06 43 UT; Peak at 06:38 UT C2.1 (N04E12) between 06:54 - 07:07 UT; Peak at 07:00 UT C5.5 (N03E08) between 07:41 - 08:10 UT; Peak at 07:59 UT Fe XII running difference images show discernible brightenings on AR 0652 at 06:36 UT and 07:48 UT (no images between 06:48 - 07:13 UT). No significant dimming or wave is observed in association with the C-class events. This event has therefore been determined, from a global point of view, as a faint 'full' halo CME. 08:54 UT S West Ragged loop front that fades throughout C2. 11:54 UT S Pole Diffuse and ragged loop front followed at 12:30 UT by a small bright front and gusty outflow. At ~14:30 UT in the gusty outflow begins to be discernible a loop front. It fades throughout C3. 13:54 UT WN West Very faint elongated and ragged loop front. It fades throughout C2. 17:54 UT NN East Faint and diffuse jet-like front that quickly fades. 17:54 UT S Pole Spray front followed at ~ 19:34 UT by a kind of asymmetric loop front. They both fade throughout C3. C3.2 X-ray flare on NOAA AR 0652 (N04E07) between 17:17 - 17:37 UT (Peak at 17:24 UT). 23:54 UT SS West Diffuse and not well defined loop front. At 00:06 UT on next day, bright narrow feature superposed with the loop's leg on the S Pole. Gusty outflow follows toward S. At 01:54 and 02:30 UT couple of asymmetric loop fronts developing toward SSW. GOES recorded C- and M-class X-ray flares by the time: C4.1 (N03E04) between 22:01 - 22:18 UT; Peak at 22:12 UT M1.6 (N04E03) between 22:40 - 23:07 UT; Peak at 22:58 UT C1.3 (N03E02) between 23:09 - 23:45 UT; Peak at 23:21 UT Fe XII running difference images show discernible brightenings on AR 0652 at 22:12 UT and 23:24 UT (no images between 22:36 - 23:12 UT).
03:30 UT W Limb Very very slow development of an apparently twisted structure. 03:54 UT E Limb Ragged loop front. Superposed with it, a very diffuse and faint loop-like feature seems seems to develop, moving faster. Barely visible in C3. 07:31 UT S West Diffuse and not well defined loop front. Difficult to give an exact time of first appearance. Faint and diffuse loop-like front starting at ~08:30 UT above the W Limb. GOES recorded C-class X-ray flares by the time: C2.3 (N03W04) between 06:41 - 07:02 UT; Peak at 06:48 UT C4.3 (N03W04) between 07:17 - 07:36 UT; Peak at 07:26 UT Fe XII running difference images show discernible brightenings on AR 0652 at 06:48 UT and 07:36 UT.
