SOHO/LASCO HALO CME 111127 BACKSIDED UCMEO 93001 11128 1640/ 11127 61400 81854 0952/ 094// 113// 30711 11127 71326 81406 ///// ///// 1112/ 99999 PLAIN SOHO/LASCO observed a HALO CME on November 27, 2011. Event is first seen in C2 at 14:00 UT as a faint loop front over the east. The continues into the C3 field beginning 14:42 to 18:54 UT where it dissipates at 12.9 Rsun. Time/height measurements were marked at 5 points in C2 with speeds of 639.0 Km/sec at position angle 94 degrees. The event is marked to 3 points in C3. Speeds average through both fields to 711.3 Km/sec at PA 96 degrees. Acceleration of 9.59 m/sec^2. STEREO: Beacon data COR2 B, 14:25 UT a burst expanding over the east. Preliminary time/height measure gives 422.9 km/sec velocity at LE. EUVI B, 13:26-14:06 UT CME from an AR near east limb on equator line. COR2 A, 13:54 UT burst expanding over the west field. Preliminary time/height measure gives 453.5 km/sec velocity at LE. EUVI A, 13:25 UT, large expanding CME over west limb. The observation of this event is considered 'FAIR'. This CME is determined a BACKSIDED event.
