Note: This CME is seen to the NW in SOHO LASCO C2, C3 and STEREO A COR2 imagery. It appears to have a faint shock front with separate core/bulk portion. The source for this CME is unclear due to multiple eruptions occurring on the Earth-facing disk, including a filament eruption that may have triggered a flare or very bright post-eruptive arcade. The filament eruption stretched across the NE quadrant of the disk, just North of AR13192 (N15W64) towards the northern pole (N60W10). There were multiple filamentary material portions that erupted around the same time in this area followed by a bright post-eruptive arcade that was picked up as a C9.4 class flare from AR13192. These eruptions are all visible in SDO/AIA 304, 193, 171, and 094. It is unclear at this time which of these is the source for this CME.

These parameters are very preliminary. They are based off of mostly SOHO LASCO C2 and STEREO A COR2 difference imagery. The CME is partially obscured in SOHO LASCO C3 due to the spacecraft's arm seen in the coronagraph. Measured longitudes varied ~+/- 10 degrees. Updated parameters may be made with more SOHO LASCO and STEREO A imagery. |
