Remarks -
Delayed Sound
Observation Yes
Remarks I thought it was a clap of thunder, but intensely loud. I also haven't been given a chance to enter text til now, but I would like to say that the information I've given is a best estimate of what I saw a) because it was partly cloudy and some of my view was obstructed and b) Because I was driving when I saw the light. The boom happened about 5-7 seconds after the light appeared. I only noticed the orange glow at first, but then noticed the quick but gradual increase in brightness. I originally thought it was a dramatic strike of lightning, but it was a single occurrence.

Remarks It was hidden behind clouds, so I'm not sure if the brightness and then sudden disappearance was a terminal flash or if it simply went out of view.
