I didn't know, but this was a few days (1-2) before the ISS feed cut off in June 2015. I wouldn't have thought twice about telling anyone besides my husband, if not for NASA doing that. It was a very quick moment. I was outside smoking, my backyard facing south. I know it was late at night, somewhere between the 11pm-12:30am and there are few lights, any lights, out here. I noticed a bright light in the corner of my eye, by the time my eyes registered the light/movement and moved to the location of it, then spotted the light again, it had moved an incredible distance away. The only reason I know this was, the sky lit up, like a lightening strike, then there was a doughnut shape cloud, with a smaller circle in it, and a pinpoint in the center. Then it was gone. The sky was normal. I had to make myself, even though I believe there are things out there, that I just saw this. I sat for about 5 min looking for something else to happen. Even though I believe, I was still in shock that I saw this.
