It's big and it is almost certainly headed our way. I just went to the LASCO C3 satellite to see if the CME had a halo pattern, meaning it's aimed at us, and it does, as seen in this cap. The bulk seems to be high, but a lot could be hidden by the occlusion disk.
How big and when will be for the solar wx pros to determine and you can bet they're on this on right now.
