N West Since early in the day, very slow development of a expanding system of loops along the streamer. It is difficult to give an exact time of first appearance. By the end of the 'leading edge' is close to the outer edge of the C2 FOV. 03:06 UT W Limb Elongated spray-like front that fades throughout C3. It is followed at 05:30 by an elongated and 'sharp' expanding loop front. It also fades throughout C3. 03:54 UT WN west Another elongated spray-like front. It fades very close to the inner edge of C3.
02:06 UT W Limb Kind of 'explosive' (and initially bright) ragged loop front. Infalling material afterward. Pushed material superposed in the LOS on NW with the slow development of the system of loops reported in previous day. The event fades throughout C2. GOES reported an M2.8 X-ray flare from NOAA AR 0691 (N12W75) between 01:23 - 01:37 UT with peak emission at 01:33 UT. EIT 195 images show a strong brightening on NOAA AR 0691 at -1:36 UT and a big CME signature afterward, all above the western Limb. 03:54 UT EN East Bright loop front with a very faint and diffuse extension all above the SE Limb and S Pole. It develops toward NE as a bright loop front, the southern leg much fainter than the rest. By 04:30 UT, a ragged front begins to be seen above the S Pole. Its evolution show that this front seems to extend all above the W Limb, N Pole, and NE Limb, looking like a second front in the C2 FOV (just behind the original one at 03:54 UT) on NE. The event was first seen on C3 above the E Limb, developing afterward mainly toward NE as an asymmetric loop front. The event looks pretty faint on SE, S, SW, and W. By the time the LE on NE reaches the outer edge of C3 (about 10:42 UT), the event looks like a partial halo, spanning ~ 135 deg from PA 330 - 105. However, in C2 one could say that the event (bulk of the mass plus eventual shock) covers completely the occultor. The mean plane-of-sky speed of the LE of the front at PA 49 was ~ 750 km/sec (based on C3 data) showing practically no acceleration. GOES reported an M1.6 X-ray flare on NOAA AR 10696 (N09E45) between 03:23 - 03:57 with peak emission at 03:35 UT, most likely associated to the event described above. On the other hand, EIT 195 images show a strong brightening on the aforementioned AR at 03:36 UT, followed by an intensity disturbance travelling mainly toward NE, jointly with a wave-like disturbance travelling partially across the disk with apparent epicenter on AR 10696. In summary and based on its appearance in the C3 FOV, the event has therefore been determined as a partial halo CME, frontsided. 16:06 UT EN East Full halo... (more to come... tomorrow's report)
