Early estimates for a glancing blow from the CME are for approx 1800 UTC, which is noon Alaska time on Oct 2. As it looks now, we may see a good show Oct 2 as soon as it gets dark in Canada, Alaska, and maybe the upper portion of the lower 48 (MN, MI, ND, etc). Some sites at this time are reporting a direct hit. More info to follow in the next day.
What is a glancing blow? The activity on the sun won’t directly affect us on earth, rather, it will side-swipe us, which is still pretty good for auroras.
What is a CME? A Coronal Mass Ejection, a major solar eruption.
