2. CME

2.1. A. Candidate A
A.1. LASCO:
#CME 2012/09/28 00:12 UT (from CDAW)
angle: 360, velocity: 947 km/s


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

A.3. AIA & GOES
related with C3.7 class flare from AR 11577 (23:36; N06W34)

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



2.1. B. Candidate B
B.1. LASCO:
#CME 2012/09/26 11:00 UT (from CDAW)
angle: 115, velocity: 259 km/s


B.2. STEREO:
Narrow CME in both COR2-A and COR2-B. Front side moving CME, moving southward


B.3. AIA & GOES
Eruption from ~N31E07, not associated with any major flare

B.4. Comment:
unlikely to be related to the disturbance due to the propagation direction
