Update, Feb. 3 at 11 a.m. ET: The monster sunspot region 4366 is now facing Earth, and shows no signs of weakening. It is the most active sunspot of the current solar cycle (cycle 25). NOAA predicts that a glancing blow from a massive CME released toward Earth is likely this week. A minor (G1) geomagnetic storm is predicted to begin on Thursday (Feb. 5), with possible auroras at lower latitudes than usual. Stay tuned for more information.
