an oval, double disk, with green & red lights lights appeared near full moon and Jupiter.

I was gazing upon the full moon and Jupiter when the slowly moving double-oval disk, one with green and the other with red light appeared. Moving extremely slowly, almost hovering, it took time to realize its movement. To confirm it was not a window reflection, I exited my room into the dark night. The sighting was verified by another guest. I stopped viewing before its disappearance because I was in sheer pajamas and did not want to be seen. I was attending a retreat at Mepkin Abbey, a Trappist monastery of the Cistercian Order, located on an 18th century 7,000 acre rice plantation.
