The Northern Lights might be making a surprise appearance across much of the U.S. tonight thanks to a severe geomagnetic storm! If you’re north of Georgia or SoCal, step outside after 8 p.m. ET and you could catch a colorful aurora show—think green, purple, or even red glows. No promises, but it’s worth a peek (and your phone camera might catch more than your eyes). Who else is staying up for this? #Science #NorthernLights #AuroraBorealis
