G1-Mionor geomagnetic storm conditions were observed on 15 Feb, following the likely arrival of a coronal mass ejection (CME) that departed the Sun on 11 Feb. Reports were received of aurora being observed from places like Great Falls, MT over night. See the associated graphic for details on potential impacts, as well as possible viewing opportunities in the coming hours. As always, stay tuned to this page for updates.
