Northern Lights Tonight

Look to the skies tonight and early morning August 4th for the Northern Lights (or aurorae). The Sun’s surface has erupted and blasted tons of plasma (ionized atoms) into interplanetary space. That plasma is headed our way, and when it arrives, it could create a spectacular light show.
Aurorae normally are visible only at high latitudes. However, during a geomagnetic storm aurorae can light up the sky at lower latitudes. Sky watchers in the northern U.S. and other countries should look toward the north on the evening of August 3rd/4th for rippling “curtains” of green and red light.
“It’s the first major Earth-directed eruption in quite some time” said astronomer Leon Golub of the Harvard-Smithsonian Center for Astrophysics (CfA).
