Well, it didn't look much bigger, certainly. I read something like 20%.
Fun fact (and not saying you don't know this, red 31, just rambling): Where the moon is in the sky doesn't really matter, though. Beware the famous Moon illusion. The moon above you is the same size as the one on the horizon, but because of the way the animal brain maps the sky, it looks much larger at the horizon. You can prove it to yourself by tracing it on a piece of paper at the horizon and then directly above you. Even when you know, you can't shake the illusion, either. It still looks way bigger at the horizon.
