UFO Sighting in Chesterfield, Virginia on October 13th 2015 – Light in the early morning starlight sky appeared for only a second like an explosion

I woke up went outside (backyard) to have a cigarette. The time was exactly 615am (looked at clock after I saw the light). I was looking high into the dark early morning sky at the stars, and after a few seconds, I saw a light, slightly bigger than the largest star I could see at that time. This light was stationary, and came from a point where there was no star, got extremely bright and faded out all within one second very similar to seeing an explosion far off in space. When it went out, I looked at the time and it was 615am exactly and noticed that the spot I saw the light, was completely dark just like it was before it appeared. Don't know if it was a UFO, some kind of explosion in space, an impact of two asteroids, a super nova or anything of that likeness, but I did see it and never have before or after that time. Please let me know your opinion what you think it might have been. Sorry, I wish I had more. Thank you. [Name removed/cms/tg]
