The Sun produced at least five major "halo" coronal mass ejections over a 5 day period. The associated geomagnetic storm was so intense, aurora were spotted as far south as Alabama.
The Sun produced at least five major “halo” coronal mass ejections (CMEs) over the period of Nov. 4-8, an unusually fast pace for solar activity.
