I haven’t kept track of the strength of the last coronal mass ejection, but I know you are wrong in this regard, because coronal mass ejections take around 3 to 4 days, sometimes even longer to reach earth. Other effects from solar flaring, such as x-ray particles, and high charge electrons arrive, basically, instantaneously along with light (~8m)
Wouldn't be the first time AP failed to interpret "the science".

What's the difference in appearance between these?
There is no way to predict actual solar storms that far ahead. Nor any way to predict geomagnetic effects at Earth 4 days ahead unless the sun put out a really slow, big CME (which it hasn't).
This is not news. This is a science understanding mistake made by AP News.
