- Northern Lights tonight!
AURORA WARNING: On Monday, April 15th (0400 UT), a full-halo coronal
mass ejection billowed away from the Sun. The expanding cloud is heading
toward Earth and could ignite Northern Lights (most likely at high
latitudes but possibly at mid-latitudes as well) when it sweeps past our
planet on April 17th or 18th. Visit spaceweather.com for updates.
