Based on maximum speed of 390 km/s, the search window starts from 2012/04/17 03:20 UT
2012/04/17
==> CME at 14:12 UT (angular width 89), moving with 327 km/s
Moderate CME in both COR2-A and COR2-B, frontside moving
Filament eruption from ~N24W46, not associated with any major flare.
Unlikely the source of disturbance due to the location of eruption and propagation direction of CME.
==> CME at 17:36 UT (angular width 103), moving with 167 km/s
Not a frontside moving CME, from COR1 data
2012/04/18
==> Partial halo CME at 02:48 (angular width >271), poor event moving with 352 km/s(CDAW)
not a frontside moving CME
==> Partial Halo CME at 09:24 UT (angular width 215), moving with 448 km/s
not a frontside moving CME
==> Partial Halo CME at 15:12 UT (angular width 184), moving with 840 km/s
not a frontside moving CME
==> Partial Halo CME at 17:24 UT (angular width 147), moving with 581 km/s
Moderate CME in COR2-A and COR2-B, frontside moving CME
Eruption from AR 1463, associated with C5.3 class flare (S27W30)
comment: an earlier eruption from the same AR (at 13:36)
could be the source of disturbance.
2012/04/19
==> Partial Halo CME at 02:48 UT (angular width 108), moving with 141 km/s
Not distinguishable in COR2-A and COR2-B
unlikely the source of disturbance due to the initial propagation speed
==> Partial Halo CME at 15:12 UT (angular width 142), moving with 540 km/s
Major CME in both COR2-A and COR2-B, frontside moving CME
Filament eruption ~S19E42, not associated with any major flare
could be the source of disturbance
2012/04/20
==> Partial Halo CME at 02:48 UT (angular width 148), moving with 257 km/s
unlikely the source of disturbance due to the initial propagation speed
==> Partial Halo CME at 17:00 UT (angular width 131), moving with 171 km/s
unlikely the source of disturbance due to the initial propagation speed
2012/04/21
No CMEs on this day seem to be related to the disturbance on 2012/04/23 due to the time and speed of eruption.
