2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2012/06/14 14:12 UT, halo CME (from CDAW)
angle: 360, velocity: 987 km/s


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


A.3. AIA & GOES
Eruption from AR 11504 (S19E06), associated with M1.9 class flare

A.4. Comment:
Likely to be related to the disturbance.
