I was outside, the sky was very clear and blue. I witnessed a very bright flash in the NW sky. It last for only a second or two, it was a verticle flash with what seemed like sparks coming from it. There was a puff of smoke in the sky for several minutes afterward. ((NUFORC Note: Probable meteor?? A rather dramatic meteor was reported to the American Meteor Society website for the approximate time period indicated by this report. PD))
