SOHO/LASCO Partial HALO CME 121127 UCMEO 93001 21127 1830/ 21127 60248 80842 3241/ 190// 323// 40930 21127 60206 80451 15215 ///// 2112/ 99999 PLAIN SOHO/LASCO observed a partial HALO CME on November 27, 2012. Event is first seen in C2 beginning 02:48 UT with a loop over the NE with cavity and core. The event expands with extensions PA 324 - 190 for a total width of 226 degrees wide. The event continues into the C3 field beginning 03:18-08:42 UT out to the edge of field at 30 Rsun in the Northeast. Time/height measurements were marked at 4 points in C2 with speeds of 828.2 Km/sec at pa 50 degrees. The event is marked to 13 points in C3. Speeds average through both fields to 929.9 Km/sec at PA 50 degrees. Acceleration 7.94 m/sec^2. SDO AIA 193 and 304 shows activated prominence material near the limb in the NE at location [N22, E65] beginning 01:00 UT. Eruption begins 02:06-04:51 UT along with flaring of area at [N15, E52]. The event produces a dimming and small wave along with a post loop arcade. STEREO: BEACON data COR2 B, 03:55 UT in progress, an expanding loop over the West hemisphere. Preliminary time/height measure gives 575.3 km/sec velocity at LE. EUVI B 195, 11/26 16:16-01:46 UT data gap. Region on West limb with brightening and post arcade. COR2 A, 00:00-05:24 UT Data gap. At first frame, asymmetric HALO near edge of field. EUVI A 195, n/a The observation of this event is considered 'GOOD'. This CME is determined FRONTSIDED.
