Tonight's Supermoon Eclipse Explained

By NASA in this short, amusing clip:

Nothing spooky, just straightforward orbital mechanics resulting in some nice sky-scenery tonight.  Unfortunately the local weather may not cooperate, but  I'm still going to go outside and take a look.

ps: Looked, saw nothing but clouds.
pps: You want a sure cosmic sign of approaching doom?  I bought a Windows laptop this morning.  OK, now you can go freak out.  Expect a report, including a part on "why?," on this upcoming fiasco in a couple of weeks.
