The date and time is pretty general, but I vividly recall waking up during the night and moving to sit in the bay window of my bedroom. I did this often as a kid (I was about 8 when this happened).

I watched a "relatively small and extremely low" lightning cloud in what was otherwise a clear sky.  It was approximately one hundred feet off the ground, and moving very slowly.  It seemed to stop in mid sky and turn right, silently moving until out of sight.
I vaguely recall getting into bed after what seemed to be a short time sitting at the window, but the sky was getting brighter.  I know it was quite late at night when I sat at the window because I was having a hard time falling asleep.
Witness indicates that the date of the event is approximate.  PD
