Daylight Lights
Mass ejection resulted in a daylight aurora. The sky looked like a funky heat signature image. It was brief and very localized; I’m glad I paid attention to the weather channel today. There might be more to come.

"Eta Carinae isn't actually exploding. It will explode someday, but for the time being the star is simply undergoing what astronomers call "mass ejection." The core of this particular star produces energy (from fusion) at such a prodigious rate that the amount of photon energy created exceeds what is called the Eddington limit. The light of the star is exerting so much pressure on outer layers of the stellar envelope that the material on the surface becomes gravitationally unbound. Literally, the star is so bright it is blowing off it's outer shell at 1e6 km/h. "
