Remarks For a few seconds it appeared to be a big ball of light with a glow suspended in the sky, then it started moving from left to right. I thought it was going to hit the earth, in our town, but then it quickly dissipated. I guessed it was a comet, the other person in the car thought it might have been a rocket due to its trajectory. He saw it before I did. I have never seen anything like it before.
