Aurora Bump Tonight, Storm Expected This Weekend Sept. 27-28 NASA

The sun sneezed on Sept. 20 and blew a bunch of electrons and protons into space in a coronal mass ejection. That material is expected to arrive later this afternoon and evening and potentially spark a minor display of the northern lights. Skywatchers in the fringes of the northern U.S. and across Canada should be on the watch tonight from nightfall till around midnight. I suspect we’ll see a glow or possibly a bright arc low in the northern sky from northern Minnesota, Michigan and Wisconsin.
