metallic disk emerged from one cloud and disappeared behind another.

I assume my sighting correlates to another sighting on this date, in this city. Beyond the other witnesses account, I could only guess it was summer (due to the fact that it was still light outside at 7:30 pm) and that it was 1979 or so (based on my age at the time).
My older sister and I had been sent to bed early for misbehavior that evening. We were in the back bedroom of a single story duplex on Toulon Dr. in Baton Rouge. Out the back window of the room we saw a large metallic (silver-grey but not shiny) disk with round windows around the upper edge which were amber orange-yellow in color. It emerged from behind a cloud and moved slowly across the sky and into another cloud. During the time we watched and waited, it didn't emerge from the second cloud. The clouds were low puffy white clouds, otherwise the sky was blue, it was early dusk so it was light but not direct sunlight.
I couldn't say how high it was in the sky, but it was low enough to see in great detail that it was a disk, that it did have windows (portholes) and that it was not in any way shaped like known aircraft. It was lower than we ever saw planes in that area.
The craft moved much slower than you would expect a plane to fly. We heard no noise from inside the house.
Being kids and already in trouble, we told our family, but were sent back to bed.
Witness indicates that the date of the incident is approximate.  PD
