It would be number 2. People would think it would be 1, but it's actually too much covered by clouds.

I am thinking #1, as I was in Annapolis Saturday evening and that is what the sunset looked like in Annapolis on Saturday.

I think it's number 4

It's #1. The sun is higher in the sky, and the cloud formation further away. In #2 the sun is lower and the cloud formation has moved further east toward the camera.
