Aurorae headed this way

The Sun’s surface has erupted recently and the plasma is headed this way.

“This eruption is directed right at us, and is expected to get here early in the day on August 4th,” said astronomer Leon Golub of the Harvard-Smithsonian Center for Astrophysics (CfA). “It’s the first major Earth-directed eruption in quite some time.”

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.

That means tonight. Watch for it.
