Subject: SOHO/LASCO HALO CME 130929 UCMEO 93001 30930 2214/ 30929 62212 80318 3111/ 310// 333// 41026 30929 62112 80230 42523 ///// 2112/ 99999 PLAIN SOHO/LASCO observed a HALO CME on September 29, 2013. Event is first seen in C2 at 22:12 UT as a loop on the Northwest. A full asymmetric HALO develops with cavity and core by 23:12 UT. The event continues into the C3 field beginning 22:30 to 03:18 UT leaving the C3 field at 30 Rsun in the West. There is increased proton flux seen in the LASCO C2 and C3 field of view. Time/height measurements were marked to 3 points in C2 with speeds of 896.7 Km/sec at position angle 311 degrees. The event is marked to11 points in C3. Speeds average through both fields to 1025.7 Km/sec at PA 311 degrees. Acceleration -15.17 m/sec^2. SDO/AIA : 193A and 304A show activation along a filament beginning 18:18 UT on disk centered at location [N23, W25]. The filament erupts at 21:12 UT producing dual ribbon flare with dimming across the West hemisphere and long duration post arcade. Shown while analyzing the full resolution AIA 193 data, a bi-pole region of emerging flux begins development early in the day on 9/29/13. This region located [N18, W26] at a barb along the filament is associated with the eruptive filament. (JHV JHelioviewer movie) STEREO: Beacon Data COR2 B, 22:25-00:55 UT asymmetric halo over the West. Preliminary time/height measure gives 1097.4 km/sec velocity at LE. EUVI B, n/a. COR2 A, 15:54-03:54 UT data gap. In progress, CME out to of FOV. EUVI B, n/a. NOAA reports a long duration C1.2 Xray flare 21:43/23:39/01:03 UT. GOES shows an increase of proton flux in all three channels with the increase of particles >10MeV above solar storm levels. The observation of this event is considered 'Good'. This CME is determined a FRONTSIDED event.
