Though it was a shooting star, but was brighter and larger than usual.I was driving my car about 20-25 mph on a side street when suddenly I saw what looked like a shooting star. It flew over head in a pretty straight line heading North. It looked very high up in the sky therefore, I didn't see exactly what shape but it seemed like a sphere, but again it was moving incredibly fast. I have seen shooting stars before and this was larger and much brighter and closer to earth than a star. The object was a bright blue color that left a trail. So in conclusion to me and my friend who observed this at the same time, this seemed more like a UFO sighting than a shooting star, or any type of plane. I have never seen anything like this. It was basically gone in a blink of an eye.
