My wife and i were watching fireworks and aircraft in our backyard on the 4th while we were swimming. when we got out of the pool and were drying off, i noticed a red light several miles away to the southeast approximately 1000 ft in the air. it caught my attention because the light was red and was the only light i saw. usually, starboard wing lights are red and the opposite is green. this had no other light but red. however, i thought perhaps it would become clear to what it was as it approached, but it approached fast and as it went directly over our home, my wife and i could see the red light was circular with a black hole inside it. it then climbed out of sight as it went northeast. it made no sound and traveled the entire valley in less than 30 seconds.
