Today when driving to work, a big flash of light for about 2 seconds surprised me. Initially I though was part of the stormy weather we are having lately here in New Jersey. Sky was dark an totally cloudy. The light changed in white, magenta and blue, it had a point where this light was more concentrated, about 20 to 30 degrees north.

My location was Rt. 17 (NJ), going north, close to Carlstadt .
Time : Close to 05:00.

Because it turned in different colors, I wonder if it could be a sort of EM discharge or maybe a fireball.

Thanks ahead.

Could be HAARP! Just my two cents

Maybe a transformer blowing? Last winter mysterious colored flashes were reported in MD. It was just transformers blowing out. I used to live near a particularly shoddy one. I could always count on a good light show.

Thanks for the answers. Yeah, transformers can create similar effects, but this light was huge and looked like it was behind the clouds. I think it was a fireball probably. Just hoping someone else saw it.
