What could make a summer weekend with clear skies even more perfect? How about the northern lights?
The chances of seeing auroral displays are better than usual tonight and Sunday night. That’s due to a geomagnetic storm that’s expected to sweep past Earth this weekend.
The storm was spawned on July 13 by an outburst of electrically charged particles from the sun, known as a coronal mass ejection or CME. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center says the outburst is directed at Earth, and the peak of the wave should arrive sometime on Sunday.
The most violent outbursts have been known to disrupt satellite communications and power grids, but this one is expected to be merely moderate to strong – producing heightened auroras but no big disruptions.
For most people, the big questions are: Can I see the aurora? And if so, where and when?
