APOD 4.20

A Flag Shaped Aurora Over Sweden

See Explanation.  Clicking on the picture will download
 the highest resolution version available.

50 km tall, this astounding aurora displayed itself in the night sky of Sweden on March 30, 2015. (Image credit goes to Mia StÃ¥lnacke) Caused by coronal mass ejection, the aurora shows multiple different colors of light that happen to appear in the shape and pattern of a flag.  Completely random chances of getting a familiar shape or pattern!

Godspeed,
Melanie
