Subject: SOHO/LASCO HALO CME 130830 UCMEO 93001 30830 1340/ 30830 60248 90630 0631/ 062// 333// 41071 30830 60206 80339 14313 11836 1112/ 99999 PLAIN SOHO/LASCO observed an asymmetric HALO CME on August 30, 2013. Event is first seen in C2 at 02:48 UT as a bright loop over the East. The event expands with extensions to a full halo by 03:12 UT. The event continues into the C3 field beginning 03:06 to 06:30 UT in progress at last frame before end of contact with SOHO. Time/height measurements were marked to 2 points in C2 with speeds of 1005.3 Km/sec at position angle 63 degrees. The event is marked to 8 points in C3. Speeds average through both fields to 1070.9 Km/sec at PA 63 degrees. Acceleration 0.99 m/sec^2. SDO/AIA 193A shows a flare of AR 11836 at location [N13, E43] beginning 02:06-03:39 UT. The flare produces a dimming and a wave over the East and North hemispheres with post loop arcade. STEREO: BEACON Data COR2 B, 02:39-05:39 UT expanding partial halo CME over the West. Preliminary time/height measure gives 1053.2 km/sec velocity at LE. EUVI B, 01:56-03:06 UT flare with CME over West limb with wave traveling along limb. COR2 A, 21:54-03:24 UT data gap. In progress at first frame, expanding symmetric halo. Preliminary time/height measure gives 553.5 km/sec velocity at LE. EUVI A, n/a. NOAA reports a long duration C8.2 Xray flare 02:04/02:46/04:06 UT from AR 11836 at location [N13, E43] The observation of this event is considered 'GOOD'. This CME is determined a FRONTSIDED event.
