Reports Report 3901g (Event 3901-2020)

Observer
Name Sharon L
Experience Level 3/5
Remarks I’ve observed some spectacular meteor showers, but I’ve never seen a light like this in the sky. I was swimming, facing East, when I saw a bright yellow light appear in the NE sky In my peripheral vision. I looked up, initially thinking there was an aircraft flying across, but it moved so fast I knew it couldn’t be. Within about 3.5 seconds it had crossed my entire field of view from the NE to the SE, and then the entire streak was gone, like a switch had been flipped. I immediately grabbed my phone from the edge of the pool so I could note the time in the hopes that I would find other reporting, but I have not. It didn’t curve toward the horizon. For the seconds that the entire line appeared it was perfectly horizontal in the eastern sky.

Remarks The train was a bright yellow, solid line, horizontal across the sky. It looked like someone was writing in the sky with a laser pointer - extremely bright, straight, and solid (not fuzzy). I don’t really know how to estimate the length of the train with degrees - for a couple seconds it crossed the entire eastern sky, and then was entirely gone.
