Medoc Campaign started on May 16. Since then SOHO is in Telemetry submode 5. EIT 195 CME watch at half resolution (512x512).
03:06 UT WS West Initially bright ragged front. The event fades close to the inner edge of C3. EIT 195 images show ejection of material on the WSW Limb from barely behind the disk between 02:24 - 03:36 UT. 03:50 UT HALO Extremely faint and diffuse brightening all around the occulting disk (though not very clear at this time). Please note that since 03:06 UT an (initially) bright ragged front was seen above the WSW Limb, fading out then close to the inner edge of C3. This particular feature corresponds to ejection of material seen by EIT 195 on the WSW Limb from barely behind the disk between 02:24 - 03:36 UT and should not be confused with the main event. Coming back to the halo event... the event in itself is so faint that is barely discernible in C3, where one can say that it is first discerned at around 08:18 UT. A very rough estimation of the mean plane-of-sky speed of the LE of the event based on C2 data (where at least it is possible to measure something) is ~ 300 km/sec (at PA 211). GOES reported an M1.8 X-ray flare from NOAA AR 10763 (S15W00) between 02:31 - 02:52 UT with peak emission at 02:39 UT. EIT 195 images show a strong brightening at 02:36 UT on the aforementioned AR. A clear wave is seen then developing toward N, W, S, and SE of the AR between 02:48 - 03:36 UT. Also a dimming region to N and S of the AR. The AR continued flaring afterward (at the time of writing: a C8.4 peaking at 04:03 UT, and a C2.8 peaking at 05:53 UT). In summary, the event has therefore been determined as a very faint Full Halo CME, frontsided, associated with an M-class X-ray flare on NOAA AR 10763. 07:27 UT ES East Small loop front along streamer. It fades throughout C2. 12:26 UT W Limb Diffuse and very asymmetric loop front that fades close to the inner edge of C3. It is followed at ~ 15:50 UT by a very faint ragged front on WNW that fades throughout C3. Gusty outflow. 21:26 UT ES East Diffuse and very faint loop front. It fades throughout C2.
00:26 UT S East Very faint and diffuse expanding loop front. It fades throughout C3. 02:06 UT S West Bright and ragged loop front. Infalling features in the trailing material on WSW. EIT 195 images show a signatures of a big backsided CME above the SW Limb starting at around 01:36 UT. Time of the last C2 image analized: 12:06 UT
