I was watching the earthcam lauderdale by the sea (florida) live stream. there was what appeared to be a single black cloud with dark gray around it at the center of the frame, in the sky above the pier. it looked as if it were drawn of coal, with a black nucleus and dark gray around the nucleus. it did not have a sharpness, it was more fuzzy, like a coal drawing. it was oval, as opposed to circular. the oval was side to side, not top to bottom. i thought that it might be something stuck on the camera lens, but it just didn't seem so, so i just figured it to be an unusual singular cloud in an otherwise clear sky. i watched the calm beach scene for several minutes. the cloud did not move, when suddenly, and had i blinked, i might have missed it, the cloud warp sped, dipping and rising in a slight arc, toward land and to the right and off the frame. i had probably begun watching 4 or 5 minutes before it sped off at 10:09 am today, april 27, 2020.
