As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at approximately 2145 UT on Nov. 28th. The impact was weaker than expected, but it still produced bright auroras around the Arctic Circle.

NOAA/SWPC Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active with a chance for minor storm periods on days 1-2 (29-30 November). Activity is due to a combination of a coronal hole high speed stream (CH HSS) and the coronal mass ejection (CME) from 26/0712Z. On day 3 (01 December) mostly quiet to unsettled conditions are expected.
Active auroral displays will be visible overhead from Barrow to Anchorage and Juneau, and visible low on the horizon from King Salmon and Prince Rupert. Alaska Geophysical Institute Aurora Forecast
