I was ascending a external staircase from our basement.
When above me in the dark evening sky, a very large, wide cylinder appeared momentarily.
It 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 faded out.
It took only a moment it seemed to me, was gone as quickly as it appeared.
There were no marks or details obvious.
It was an orange glow in the 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.
