ATLANTA, Ga. -- Strong storms moved through the metro Atlanta area early Sunday, knocking out power to some areas.

Most of the outages were in the Mableton area, where 1,675 residents were without power at one point after lightning reportedly struck a transmitter, but many of those outages were quickly restored.

Another large outage was near Roswell Road, where about 400 customers lost power.

(USA Today) -- A solar flare that launched off the sun Wednesday afternoon could wreak havoc with communications systems and power systems on the Earth, as well as with satellites in orbit, in coming days.

Forecasters with NOAA's Space Weather Prediction Center said the flare already "caused impacts to high-frequency radio communications on Earth today," according to NOAA. "A coronal mass ejection (CME) associated with this event is likely, but further analysis is necessary to determine whether it will produce geomagnetic storming on Earth."
