A.2. STEREO:
Major CME in both COR2-A and COR2-B, front side moving CME.
A.3. AIA & GOES:
Eruption near the AR 11619 (inter ARs; ~N11W24), it was not associated with any major flare.
A.4. Comment:
Could be the source of disturbance.
2.1. A. Candidate B
B.1. LASCO:
#CME 2012/11/21 08:37 UT, Halo CME (from CDAW)
angle: 142; velocity 410 km/s
B.2. STEREO:
Major CME in both COR2-A and COR2-B, front side moving CME.
B.3. AIA & GOES:
Associated with M1.4 class flare from AR 11618 (~06:45, flare starting time)
B.4. Comment:
less likely to be related to the disturbance due to the time of eruption and propagation speed.
2.1. A. Candidate C
C.1. LASCO:
#CME 2012/11/21 16:00 UT, Halo (from CDAW)
angle: 360; velocity 529 km/s

C.3. AIA & GOES:
Associated with M3.5 class flare from AR 11618 (~15:10, flare starting time)
C.4. Comment:
less likely to be related to the disturbance due to the time of eruption and propagation speed.
