SOHO/LASCO observed a partial HALO CME on November 30, 2011.  Event is
first seen in C2 at 22:24 UT as a large loop front over the west. The
approximate width of the CME spans pa 216-08 degrees totaling 146 degrees wide.
The event continues into the C3 field beginning 23:06-06:42 UT to the edge
of the field of view. In the east there is scattered material and in the south near
the pole which appear as 2 separate events.

Time/height measurements were marked at 4 points in C2 with speeds of 604.8 Km/sec
at position angle 272 degrees. The event is marked to 12 points in C3.  Speeds
average through both fields to 587.5 Km/sec at PA 271 degrees. Acceleration of
0.30 m/sec^2. 

SDO AIA 193 shows a cme from AR 11360/11356 area located [N17,W59] beginning
 20:12-22:48 UT with faint dimming and wave south and east of the region. 
AIA 304 shows the same area with filament material erupting adjacent to the south
of the AR areas 20:15-22:15 UT.
STEREO: Beacon data
COR2 B,  21:25 UT an expanding CME over the north west. 
COR2 A, in progress 23:54 UT a large cme over the east field.


The observation of this event is considered 'FAIR'. This CME is determined a FRONTSIDED event.
