Based on maximum velocity of 430 km/s, the search window starts from 2013/04/26 09:10 UT. However, I searched within six days.

2013/04/24
Halo CME at 00:48 UT. It was moving with velocity of 699 km/s. At least ejecta was not moving on the front side.

Unlikely the source of disturbance of 2013/04/30 due to speed and appearance time.

2013/04/25
No CME on this day seem to be related to the disturbance of 2013/04/30

Partial halo CME at 08:48 UT, but it was moving northward.
Eruption from near the eastern limb

Unlikely the source of disturbance of 2013/04/30 due to the location of eruption.

2013/04/26
Partial halo and front side moving CME at 18:24 UT. It was moving with linear velocity of 271 km/s.

Moderate CMEs on both COR2-A and COR2-B.

SS: Large filament eruption, crossing equator, from ~W30. Not associated with any major flares.

Could be the source of the disturbance of 2013/04/30.

2013/04/27
No CME on this day seem to be related to the disturbance of 2013/04/30

2013/04/28
Partial halo CME at 13:25 UT, moving with a velocity of 400 km/s.

SS:Eruption from/behind the Eastern limb.

Unlikely to be related to the disturbance of 2013/04/30.

Front side moving CME at 21:48 UT. It was moving with linear velocity of 303 km/s.

Small/moderate CME on both COR2-A and COR2-B, fainter in COR2-B FOV.

SS: Eruption is related with C4.4 flare from AR 11735 (S17W37).

Unlikely to be related to the disturbance of 2013/04/30 due to initial speed of the eruption.



2013/04/29
Front side moving CME at 06:24 UT. It was moving with linear speed of 452 km/s.

Unlikely to be the source of disturbance due to time and speed of the CME.

2013/04/30
No CME on this day seem to be related to the disturbance of 2013/04/30, because of speed.
