2. CME
2.1. Candidate A
A.1. LASCO:
#CME 2012/11/23 13:48 UT, Halo CME (from CDAW)
angle: 360; velocity: 519 km/s

A.2. STEREO:
Major CME in both COR2-A and COR2-B. Front side moving CME.

A.3. AIA & GOES
Filament eruption from ~S38E11, not associated with any major flare.

A.4. Comment:
Could be the source of disturbance.

2.1. Candidate B
B.1. LASCO:
#CME 2012/11/22 09:48 UT, Partial Halo CME (from CDAW)
angle: 136; velocity: 819 km/s

B.2. STEREO:
Major CME in both COR2-A and COR2-B. Front side moving CME.

B.3. AIA & GOES
Eruption from decayed AR (~S22E22), not associated with any major flare.

B.4. Comment:
Less likely to be related to the disturbance, as the time of eruption is outside of the search window.
