I was ascending a external staircase from our basement. Suddenly above me in the evening dark sky, a very large, wide cylinder appeared momentarily. I moved from my right to my left as I looked up.

Also, this wide bright orange wide cylinder ballooned outward on both sides, then returned to its wide cylinder shape and suddenly faded out.  It took only a moment it seemed to me, was gone as suddenly as it appeared.  There were no marks or details obvious.  It was an orange glow in shape I have described...  Appeared and gone in a moment.  I encountered my father on our porch and he did not report to me that he had seen the event.  This is a long time ago and I cannot very well recall that we remarked to each other in detail.
