EXACTLY WHEN IS IT HAPPENING?

Actually, we already had a "Supermoon" last month. In case you missed it, there are two more: November 14 and December 13. Those are the next two full moons, and if there are no clouds, it should be quite noticeable. Of course, the moon on the 13th and 15th won't look that much different-it's a gradual thing. The moon rises at 5:20pm on November 14th, so the appearance should be amazing. It already appears to be bigger when it's near the horizon, so it will look gigantic while low in the sky right during the PM rush! It should look just about as spectacular on December 13th.
