Cary Oler expects the arrival centered around 18:00 UT
If so we can expect a storm already in progress when it gets dark over Germany and the Netherlands....

An analysis of available data suggests the CME from todays major flare may arrive centered in time around 18:00 UTC on 25 September
(which translates to 2 pm EDT on 25 September), give or take several hours.
The disturbance should last at least 24 to 36 hours, which should provide most of the world's middle latitude zones a chance to witness
activity.
