I went outside to have a cigarette. I noticed a bright light about 30 degrees up and to the south west. This only lasted about two seconds and the light went out. I see jets go by this area all the time. This was no jet. Most stars I see don't just go out. This was a clear night. What ever it was never came back on. Did I see a star blow up? UFO or what I don't know. I wish I could find out what it was. I have been looking at NASA and the ESA web sites but still no real answers.
