Randomly moving dot in AAZ0001ihn
by Nerf herder
I tagged an artifact in the lower left, but just above the center is a small dot that moves around (or 4 unrelated dots in the same area). Not sure what that is.
Looks like a hot pixel. It's movement is consistent with the common artifact movement pattern... up between frames 1 and 2, down and right between frames 2 and 3, and left between frames 3 and 4. This motion comes from the telescope taking each frame with an intentionally different area of the camera. When frames are aligned after being taken this way, artifacts move in this characteristic non-linear movement between frames, while asteroids will show up moving in a straight line.
