The incoming CME will hit Earth's magnetic field on Jan. 18th or 19th,

Well if anythings happened, I think it might have done between 0030 and
0100, but I'll probably be wrong...


Speaking as a total non-expert... I wouldn't imagine the CME would have
arrived that early. Reports I've heard suggest late today, early

tomorrow?
There was an M and an X class event before this X3.8, so I suspect the
south-wobbling of the IMF around that time would have been due to those?

Although having said that, the CME from the X3.8 did look pretty fast to

me
on the SOHO mpegs of the C2/C3 sensors, the front-end of the proton storm
hit SOHO very fast indeed compared to the earlier ones, and seems to be
still going on (looks like one hell of a storm.)

Methinks there's a lot of coronal material heading our way, darned fast.

And you would be right Julie for the CME's for those from yesterday and
Sunday, but those from Saturday were due to arrive late Sunday or during
Monday. And I think they did.
