04:06 UT HALO Signatures likely related to the event were first seen in the C2 FOV at 04:06 UT: i) a faint and diffuse loop front above the S Pole, and ii) a narrow and brighter ragged front developing toward NW preceded at 03:30 UT by ragged and not well defined narrow front. By 04:30 UT, the C2 occultor is already completely covered by a rather symmetric and diffuse halo. The signature marked as ii) is first seen in C3 at 04:18 UT surrounded by a diffuse front ahead of it. The 'halo' itself covers the C3 occultor by 05:42 UT. For reference, the mean plane-of-sky speed of the outermost front of the 'halo' at several PA was: a) PA 042: 443 km/sec, b) PA 214: 520 km/sec, and c) PA 147: 430 km/sec. As for the elongated feature in NW, the mean plane-of-sky speed at PA 318 was ~500 km/sec. EIT 195 images show a brightening on NOAA AR 10696 starting at ~02:12 UT, peaking at 02:24 UT, and followed by an intensity disturbance (CME signature) developing apparently toward N, E, and S. Another brightening can be distinguished at 03:36 UT, most likely related to C7.9 X-ray flare (see below). On the other hand, GOES recorded a C7.9 X-ray flare (during a long duration X-ray event) from NOAA AR 10696 (N08W20) between 03:25 - 03:36 UT with peak emission at 03:29 UT, possibly associated to the event related to the features described in ii). Please also note that the CME signature in EIT is before the X-ray flare. Also several optical flares from nearby the AR were reported, in particular at 02:24, 02:45, 03:00, and 03:30 UT (peak emission). In summary, the event as a whole has therefore been determined as a 'full' halo CME, frontsided. But again please keep in mind that in fact a couple of events close in space and time occurred. 07:31 UT S West Elongated loop front that fades throughout C3. 11:06 - 14:06 UT Temporary Data Gap. 14:54 UT N West Bright and fast ragged loop front. Gusty outflow well into next day. GOES reported a C7.7 X-ray flare from NOAA AR 10696 (N06W35) between 14:30 - 14:38 UT with peak emission at 14:35 UT. There is a report from NOAA of another X-ray flare afterward from the same AR: an M2.3 X-ray flare (N08W36) between 15:43 - 15:52 UT with peak emission at 15:49 UT. By 17:30 UT a very faint and not well defined front could be guessed.
01:27 UT WN West Ragged loop front followed by an elongated ragged loop front a little bit to S (at 02:50 UT). By 05:06 UT another ragged front follows. They all fade throughout C3. 09:26 UT ES East Bright loop front and trailing material.
