2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2011/01/19 ~16:00 UT, (not listed on CDAW)
angle: , velocity: 85 km/s


A.2. STEREO:
Small CME in both COR2-A and COR2-B FOV, frontside moving CME


A.3. AIA & GOES
solar source is not clear, maybe associated with the eruption on 2011/01/18 ~10:48 UT from ~S343W06.
