Location: Cedar Rapids, IA
Shape: Flash
Duration: 2-3 seconds
Bright double flash outside

At 1:35 in the morning the sky lit up like daylight in 2 flashes the first being the brightest.

I was inside a darkened room watching a DVD movie when this occurred, so I have no idea what was outside causing this phenomena.

I presumed it must have been a meteoric fireball, as the Geminids were just subsiding.
