Big coronal hole on the Sun and we are getting pummeled with charged particles - Planetary K Index is solid five and this usually spawns aurora borealis displays in the Northern United States:
From NASA's Spaceweather:
GEOMAGNETIC STORM IN PROGRESS: As predicted, a G1-class geomagnetic storm is in progress on Oct 7th as Earth enters a fast-moving stream of solar wind. The gaseous material is flowing from a large canyon-shaped hole in the sun's atmosphere. Arctic sky watchers should be alert for auroras after nightfall. There is also a chance the storm could intensify to category G2. If so, auroras could appear in the USA as far south as, e.g., Maine, Michigan and Washington. Free: Aurora alerts.
