2. CME
2.1. A. Candidate A
A.1. LASCO:
#CME 2013/03/17 15:36 UT, partial halo (from CDAW)
angle: 135, vel: 412 km/s
SEEDS C2 vel: 122 km/s

A.2. STEREO:
Seen as a major CME in both COR2-A and COR2-B.
Propagating towards north

A.3. AIA & GOES:
Long filament eruption from quite sun region (~N40W60) around ~13:30 UT. It was not associated with any major flares.

A.4. Comments:
Could be the source of disturbance on 2013/03/20. Though the eruption occurred near the limb and was moving towards the north (mostly), considering the size of filament it is possible that a small portion or disturbance could reach the Earth.



3. Other Comments
Very short event (5 hrs). The initial propagation speed of the associated CME was very small.

4. Summary
SW index: 3
Source index: 1
Overall index: 3
Filament: Yes
WDA: No
