2. CME
A.1. LASCO:

angle: 176, velocity: 229 km/s


A.2. STEREO:
Moderate CME on both COR2-A and COR2-B.

A.3. AIA & GOES:
Eruption from AR 11652. It was associated with an M1.7 class flare at N17W22. Slow moving CME, WDA is very weak


A.4. Comment:
Likely the source of disturbance due to the location of the eruption.



3. Other Comments
GMU's ENLIL run shows that eruption reached on the Earth on 2013/01/18 ~02:00 UT.

An upstream sheath is possible
