Missed your original OP, but here is my encounter.
The year was 1977. My girl and I had taken my Honda down to St. Pete Beach for a late night stroll and petting sesh.
We were laying on the beach looking up at the night sky and talking about the universe and stars we were viewing.
In almost the exact center of our view was a triangle of stars, a bit brighter than the surrounding stars, enough so, to prompt a questions from Pam, "Does that triangle of stars have a name"? I knew the three stars she was talking about because they were so much brighter than the surrounding stars and right in the middle of the view.
I answered, "Not that I know of..."
"Wow, they are so bright" Was all she replied.
About 30 seconds later the 3 stars began to move quickly, each in a path that expanded the size of the triangle, doubling it's size.
We both gasped, "Holy shit, did you see that? It just moved and doubled in size!" I said. Pam replied, "What the fuck?"
Almost as soon as she got out the word fuck, the 3 stars bolted across the sky and out of sight.
We lay there in silence for several minutes. Then petting took priority...we were young after all.
I don't much remember the petting, but the stars moving...BURNED into my brain.
