2. CME
2.1.A. Candidate A
A.1. LASCO:
#CME 2012/12/08 10:36 UT (from CDAW)
angle: 98, velocity: 104 km/s
Very faint in C2
A.2. STEREO:
Distinguishable narrow CME in both COR2-A and COR2-B, moving in the front side of the Sun.
A.3. AIA & GOES:
Eruption from decayed AR region (~S29E28), filament or hot channel structure is not observed.
A.4. Comment:
Could be the source of disturbance.
