2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2013/02/12 23:12 UT, partial halo (from CDAW)
angle: 165, velocity: 1050 km/s
SEEDS vel C2: 442 km/s
A.2. STEREO:
Seen as a major CME in COR2-A with velocity of 605 km/s. In COR2 B it was relatively weak
A.3. AIA & GOES
Eruption from ~S30W60 with very weak flare, flare class is not mentioned in 'solar monitor'. The eruption was from decayed region.
A.4. Comment:
Likely the source. However, the initial speed (CDAW) was very fast and the source location (solar surface) was near the western limb.
2.1. B. Candidate B
B.1. LASCO:
#CME 2013/02/11 11:36 UT, (from CDAW)
angle: 74, velocity: 76 km/s
B.2. STEREO:
Not identifiable in COR2 B
B.3. AIA & GOES
Not identifiable
B.4. Comment:
Could be the source.
2.2. C. Candidate C
C.1. LASCO:
#CME 2013/02/15, partial halo (from CDAW)
angle: 136 , vel: 323 km/s
C.2. Comment:
Unlikely the source of the disturbance of 2013/02/16 due to the appearance time of CME and initial velocity.
3. Other Comments
GMU's ENLIL run shows that this eruption was associated with the disturbance of 2013/02/16.
It is possible that the CME on 2013/02/12 at 23:12 UT interacted with the CME on 2013/02/11 at 11:36 UT
