W Limb Samo gusty outflow until past midday. 04:06 UT WS West Narrow ragged front. 15:30 UT W Limb Extremely faint and diffuse brightening just appearing above the W Limb . It extends up to past the N Pole by 16:30 UT. Also some extensions on S by 18:06 UT. A very ragged loop front follows on SW by ~ 17:06 UT . Finally, a system of faint loops develops on W by 18:30 UT , moving out much more slowly than . The complex event appears as a faint full halo event in the C2 FOV (though the signal in the eastern hemisphere is barely discernible). Feature  is clearly discernible in C3, where it is first seen appearing on SW by 18:18 UT. By 22:18 UT, Feature  makes its appearance above the W Limb in the C3 FOV. There is no detectable signatures of the event in the eastern hemisphere. The mean plane-of-sky speed based in both C2 and C3 (only few points at the beginning of the FOV) data is as follows: i) Feature  at PA 222: ~ 330 km/sec (showing practically no acceleration), ii) Feature  at PA 270: ~140 km/sec (showing practically no acceleration). GOES recorded a long duration C1.0 X-ray flare on NOAA AR 10875 (S17W29) between 14:33 - 16:34 UT with peak emission at 15:35 UT. EIT 195 images show the development of a frontsided CME characterized by the formation of a dimming region to S of AR 10875, then E and then N all between around 14:24 - 15:48 UT. Nice post-flare loops afterward. In summary, the event has therefore been determined as a very faint Full Halo Event (only visible in C2), frontsided, associated to a long duration C-class X-ray event on NOAA AR 10875.
