On the night of july 18, 2020, at 21:00 ct, i was setting up my telescope in my southernmost field with hopes of observing the neowise comet. due to atmospheric conditions, i was not able to see the comet at or after sunset. i was concentrating on the area directly below the big dipper as per nasa website recommendations, when i saw a solid black boxlike object, larger than a man, directly northwest of my position. its movement caught my attention as it was descending straight down, but it slowed to almost a hover. i stepped back to aim my telescope at it in order to capture a photo, but it vanished before i could sight it in. it made absolutely no sound. other neighbors in my area fly drones, but this was huge for a drone, made no sound, and was completely unlit. it seemed to "know" when i was conscious of its presence.
