open each in new tabs and flip between the 2 and you will get a better idea whats headed out away from the sun

looking here at where Earth is

then looking at the 2 HI2 images, i would say based on speed we can see this CME moving on the images, we will see the front of it arrive within around 2hrs

please keep in mind though, the very front of this CME is NOT the most dence part! and the inital hit we see will NOT indicate how bad this one will hit us
it is the plasme BEHIND the inital front that needs a close watch
