I was watching the Northern Lights last night with my boyfriend. He was looking at constellations through binoculars when I saw it. At first we were looking at a red flashing light that was moving pretty fast for an airplane. My boyfriend said that through the binoculars you could tell it was an airplane. Then, right where I had first seen the red light there was a bright light in the sky. At first it looked like a spotlight, then I notice it was shaped like a thick boomerang. It was glowing yellowish green, and very bright, I could see it very clearly. I started yelling to my boyfriend,"What is that!".He caught a quick look at it through the binoculars, but didn't spot it until right before it disappeared. It was at least 50-100 times larger than a star.
