Are we in the middle of a 2 CME event?
It is not clear if the current geomagnetic activity is from an scheduled CME (which arrived very early) or from an unknown CME, which means the scheduled CME is still due to arrive.
From the SWPC:
CME effects are expected to persist during Oct 9 then gradually subside. Analysis is inconclusive as to whether the current effects are from the CME associated with the Oct 6 filament eruption or a different, undetected CME. If they are separate events, then the CME from the filament eruption on Oct 6 is expected to arrive late on Oct 9. Solar wind conditions are expected to be influenced beginning on Oct 11 due to the onset of a coronal hole high-speed stream (CH HSS).
