"Solar blast heading our way"

The sun has unleashed a blast in Earth's direction, and that should cause brighter-than-normal auroral displays this weekend. Skywatchers won't be the only ones monitoring the storm: The folks in charge of power grids and orbiting satellites will also be on guard to make sure the disturbance in the (geomagnetic) force won't be disruptive.

Word of today's blast, technically known as a coronal mass ejection or CME, comes via's Tony Phillips. NASA says the outburst sparked an M3.2-class solar flare, as well as a stream of electrically charged particles that is due to interact with Earth's magnetic field on Saturday. "Viewers can be on the lookout for increased aurora," NASA says.
