{jpg} dot size green flash over head high altitude changes to red flash flies off SE
On the night of Sept. 23 2017 in Southern Westchester County, NY near NYS Thruway, I was sitting on my back porch listening to music. It was around 10pm EST. It was such a clear night that, when I looked directly up to the sky, I could see a few stars. I saw this one star that was brighter than the others directly above me that was slightly north of the other four stars next to it.
Approximately five minutes went by and I looked up again. That is when I saw a green light. It was the size of a dot and only slightly larger than the bright star I was looking at just a few minutes before. It appeared to be very high in altitude in the night sky. Probably thousands of feet up in the air well past the air space of regular air travel.
It was to the left of the bright star that was slightly north of the other stars in the sky and directly over head. This green dot was flashing. The green color was as vivid in color much like a traffic light. The flash was one flash per second.
I went inside to call my neighbor in order to get a second witness, but she was not home. I came back outside thinking the object had gone away, but it was still there. It then moved to the right slightly blocking the bright star.
The green flashing dot all of a sudden changed to a red flashing dot. Same tempo of flashes and red color as vivid as a stop light. For approximately one minute it flashed red and then slowly drifted east all the while flashing. It moved east until the tall oak trees in my yard blocked my vision of the object in the sky.
