The aurora borealis could be visible again across Texas, including San Antonio, on Wednesday night if current forecasts hold, according to the Space Weather Prediction Center.

On Tuesday, a G4 geomagnetic storm — the second-strongest category for these events —slammed into Earth, allowing the aurora borealis, or northern lights, to be spotted as far south as San Antonio.

Wednesday night is again shaping up to be a doozy, with “G4 conditions with a chance for higher levels” still possible tonight, according to the Space Weather Prediction Center.

Geomagnetic events happen when massive clouds of plasma and magnetic field ejections radiate from the sun and collide with Earth’s magnetosphere, which creates the colorful lights in the night sky.

For the best chance to catch a glimpse of the aurora borealis in Bexar County, folks should try to avoid well-lit areas and look north where the colorful phenomenon may be visible on the horizon.

If we’re too far south to see the lights with the naked eye, observers may be able to spot them with the long-exposure setting on a camera phone.
