Geomagnetic Storm Watch (G2-class)

Source - Space Weather News for March 25, 2017: http://spaceweather.com

GEOMAGNETIC STORM WATCH: A large canyon-shaped hole in the sun's atmosphere is facing Earth and spewing a stream of solar wind toward our planet. Estimated time of arrival: 2 to 3 days from now. This has prompted NOAA forecasters to issue a geomagnetic storm watch for March 28th when storm levels could reach category G2--that is, moderately strong. Auroras could descend from the Arctic Circle to northern-tier US states from New York to Wisconsin to Washington.
