I personally, was driving home from a boyfriend's house while on the phone with him and noticed the sky light up bright blue for just a few seconds then went away. It was only in one direction and one place, it wasn't the whole sky like when lighting strikes.My boyfriend, while on the phone with me said, "((deleted))", at the same time I did. He was looking out his bedroom window and saw a horizonal cigar shaped blue object appear and disappear within seconds. He said by the looks of it, it seemed to be about a few miles away, which would be adjectent to where I was driving.Also, upon sharing the story with other friends they too said that they saw the sky light up blue while driving about 12 miles from where I was driving at the time of the sighting. They also said the sky lit up bright blue and then went away.Another friend living about 35 miles from where I was driving saw the sky light up too. He also said it lasted only seconds and was just a part of the sky not the whole thing.These sightings all happened at the same exact time during the night, at about 12:30 a.m. on Saturday Febuary 14th, 2009. We all were in agreement that it did not look like northern lights nor did it look like lighting of any kind that we had ever seen.
