From NOAA Discussion-

.24 hr Summary...
Solar activity was low. Region 1678 (N10W40,
Dai/beta-gamma-delta)produced a C2 x-ray flare at 19/1051 UTC and
isolated B-class flares. Region 1678 showed significant development in
spots and magnetic complexity including a delta magnetic configuration
within its intermediate spots. Region 1673 (S11E17, Dac/beta) showed
gradual intermediate spot growth during the period. Region 1675 (N12W09,
Cso/beta) continued to gradually decay. The remaining spotted regions
were unremarkable. An 8-degree filament centered near N26W09 erupted
around 19/0300 UTC. This eruption was associated with an Earth-directed
partial-halo coronal mass ejection (CME) with an estimated speed of 375
km/s. The bulk of the CME material appeared to be headed northward. A
large filament, roughly 35 degrees in extent and centered near S26E15,
erupted around 19/1900 UTC. Further analysis will be required to
determine the potential geoeffectiveness of this filament eruption.

In the SDO composite images you can still see that huge filament channel. I wouldn't be surprised to see another eruption from this region.
