2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2012/10/05 02:48 UT (from CDAW)
angle: 284, velocity: 612 km/s


A.2. STEREO:
Major CME in both COR2-A and COR2-B. Front side moving CME.


A.3. AIA & GOES
Eruption from S35W29. Not associated with any major flare

A.4. Comment:
More likely to be the source of disturbance.


2.1. B. Candidate B
A.1. LASCO:
#CME 2012/10/04 15:36 UT (from CDAW)
angle: 69, velocity: 473 km/s


B.2. STEREO:
Narrow CME in both COR2-A and COR2-B. Front side moving CME.


B.3. AIA & GOES
Eruption from ~S13W07, from decayed AR. Not associated with any major flare

B.4. Comment:
Could be the source of disturbance.


2.1. C. Candidate C
C.1. LASCO:
#CME 2012/10/05 05:36 UT (from CDAW)
angle: 58, velocity: 259 km/s


C.2. STEREO:
Hard to identify in COR2


C.3. AIA & GOES
Eruption from S29W27. Not associated with any major flare
C.4. Comment:
less likely to be related to the disturbance due to location and velocity.
