I was traveling north on 495 just before exit 15. The ball seemed to just suddenly appear out of nowhere and immediately caught my eye. It traveled from right to left with a very slight arch. The train was amazing, it was so vivid and bright that I thought it was fake. Before it disappeared I could see bright blue sparks and flames clear as day. Very cool.
