SOHO Telemetry Submode changed back to Submode 5 on 2004/12/01 @ ~ 19:00 UT. EIT 195 CME watch at half resolution (512x512) since then. After the EIT Shutterles Campaign and while in Submode 6, EIT 195 CME watch at full resolution (1024x1024). SOHO Telemetry Submode changed to Submode 6 at 14:00 UT on 2004/11/30 (EIT Shutterless Campaign between 17:00 - 19:40 UT). It will be back to Submode 5 on 2004/12/01 at 19:00 UT. SOHO is in Telemetry Submode 5 since 2004/11/08 @ 22:15 UT. While in Submode 5, half resolution EIT 195 CME watch (512x512).
02:29 UT S West Faint asymmetric front. 04:53 UT NN East Jet-like front. 07:53 UT NN East At least three different features can be guessed at this time: i) a diffuse ragged front that will develop mainly toward NE-NNE, ii) a wide and ragged loop front that extends up to above the N Pole, (just appearing at this time), and iii) a bright front also just appearing on ENE that will develop as a relative narrow loop (as compared to the other two features). Both, the feature described in i) and the one in iii) are first seen in the C3 FOV at 08:18 UT, while the wide loop in ii) is first seen in C3, all above the N Pole, by 09:18 UT. The total angular spans by 10:42 UT is about 180 deg (C3), form PA ~ 270 - 090, and it matches apparently the angular span of the wide loop front [ii)]. The mean plane-of-sky speed of the LE of the different features observed is given below (based on C3 data): Feature i) : PA 036 --> 742 km/sec Feature ii) : PA 342 --> 326 km/sec Feature iii): PA 073 --> 731 km/sec GOES recorded an M1.1 X-ray flare from NOAA AR 10708 (N09E19) between 07:00 - 07:41 UT with peak emission at 07:20 UT, most likely associated to at least one of the features described above. EIT 195 images show a strong brightening on NOAA AR 10708 at 07:13 UT, followed by a rather circular intensity disturbance traveling away from the AR. In summary, the event has therefore been determined as a complex partial halo event, frontsided. But keep in mind that several features contribute to the overall morphology of the event. 18:29 UT NN West Faint loop front preceded by the development of an apparent system of faint loops. By 19:27 UT, an elongated feature develops at roughly the central PA of the loop front. As it develops it shows up as a blob-like front. A similar one at 22:06 UT (a little bit fainter).
01:27 UT EN West Faint ragged front accompanied to N by a narrow front moving apparently a little bit faster. By 02:50 UT, on NNW, a couple of blob-like fronts start to be discerned. They all fade throughout C3. Gusty outflow follows on NNW in the form of small blobs. 07:50 UT N Pole Very faint and raged front developing slightly toward NNE. It fades throughout C3. By 08:50 UT a very narrow loop-like feature (jet-like) is seen at roughly the PA of its southern leg. And by 09:26 UT another faint and ragged loop front can be seen above the N Pole.
