Orange/Red Disc UFO/UAP

The other day, I saw something strange from my window while I was watching birds at my feeder. At first I thought I saw a bright red plane coming up over the trees, but when I quickly changed position to get a better look, it appeared to be a bright orange-red, disc-shaped object, almost like a frisbee, flying up from the valley near the 360 overlook area and over my house. From my vantage point it stayed behind the tree branches, and it looked like it was tilted slightly upward as it climbed. I immediately checked Flightradar24 because I assumed it had to be a small red plane or Cessna, but there were no planes anywhere near my location. I also wondered if it could have been an afterimage from staring at my bright yellow goldfinch feeder, but the color didn’t match what I’d expect from that. I’m not claiming to know what it was, but I know what I saw: a bright orange-red disc-shaped object moving up over the trees and my house.
