Aurora Borealis

A “moderate” geomagnetic storm is forecast for the Earth on Monday, which could cause a few fluctuations to the power grid at higher latitudes and could also affect some satellites, the National Oceanic and Atmospheric Administration (NOAA) said.

The northern lights, aka the aurora borealis, could also be visible in some parts of the nation Monday night in northern-tier states from New England to Washington, according to SpaceWeather.com.

The storm is rated a “G2,” which is the second level of NOAA’s five-level storm scale. (G1 storms are minor, while G5s are considered extreme.) 

The storm is courtesy of a solar flare: On Saturday, a solar flare from a sunspot hurled a coronal mass ejection toward Earth, which is causing the geomagnetic storm Monday, SpaceWeather.com said.  

High-latitude power systems may experience voltage alarms and transformer damage could be possible if the storm lasts long enough, NOAA said.
