I just stepped outside for some fresh air and I looked at the moon. Wow, I’ve never seen this before. It looked like I was seeing two full moons with one of them looking bluish and transparent half superimposed on the other resulting in the appearance of an oblong moon.
Perhaps what you were seeing was a similar effect common to the sun when partly obscured by clouds. The clouds can cause a double image sometimes called a “mock sun”. Never heard of it happening with the moon, but I guess it can be so!
Here’s a Double Sunset over the Atacama Desert in Chile. Although I’ve never seen the phenomena, the moon is subject to the same atmospheric distortions when it gets near the horizon.
