"Solar blast heading
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 SpaceWeather.com'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.
