2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2012/08/26 10:36 UT (from CDAW)
angle: 42, velocity: 70 km/s


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


A.3. AIA & GOES
Eruption from ~S30W02 (decayed AR; maybe 11552), not associated with any major flare.

A.4. Comment:
less likely the source of disturbance due to the angular width of the CME.


2.1. A. Candidate B
B.1. LASCO:
#CME 2012/08/28 04:24 UT (from CDAW)
angle: 101, velocity: 579 km/s


B.2. STEREO:
Front side moving CME. Mostly moving northward.


B.3. AIA & GOES
Eruption from AR 11548 (~N16W42), not associated with any major flare.

B.4. Comment:
Unlikely the source of disturbance due to the propagation direction of CME.
