A supermoon is a full moon or a new moon that nearly coincides with perigee--the closest that the moon comes to the earth in its elliptic orbit--resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from earth.
Something else I'm hoping to see which I've never seen, or at least haven't seen in a very long time, and that's the Milky Way Galaxy up in the heavens...like where would it be...really, sometimes I amaze myself. (That's sarcasm directed at moi in case you didn't get it.)
Of course, since it's only the second day of my cruise, I won't be able to tell you all about it because I won't have internet access or a way to type a new post. You'll just have to wait until I return to read my exclamatory comments.
Meanwhile, feel free to imagine me at the bow of the ship, a la Rose in Titanic, looking heavenward toward the moon and the stars. Of course, depending on where my stateroom is, you could also imagine me on my verandah looking up.
