We may still see some effects from that 2nd CME, though not much so far.

NOAA-
.24 hr Summary...
Solar wind speed, measured at the ACE spacecraft, increased from
approximately 350 km/s to a maximum of 536 km/s over the period as a
co-rotating interaction followed by a coronal hole high speed stream
became geoeffective. After 25/1600 UTC, total field increased from 5 nT
to a maximum of 17 nT, while deflections in the Bz component of the
interplanetary magnetic field ranged from +16 nT to -13 nT.
.Forecast...
Solar wind speed is expected to remain enhanced on day 1 (27 Jan) as
coronal hole high speed stream effects continue combined with a possible
glancing blow from the 23 January CME. A decrease to nominal levels is
expected by days 2-3 (28-29 Jan).
