Biggest moon in nearly 20 years this weekend. So says the U.S. Naval Observatory, which reports tomorrow's 'Super Moon' will be the first since March, 1993. Some nutters predict havoc. We shrug with doubt.

The Observatory states that …

… this Full Moon will appear about as large as it possibly can as it rises on the evening of the 19th. If you watch Luna rise that night against a distant horizon dotted with trees and houses you may have a particularly good experience of the 'Moon illusion,' where Luna's disc looks enormous when close to the horizon.

Unfortunately for us Angelenos the National Weather Service warns of a “powerful late season winter storm taking aim towards Southern California” tonight through the weekend.

So maybe no Super Moon for us, unless there's a break in the clouds.

Why would Ms. Luna appear so large?

The Observatory stateth that it will be close — 221,567 miles away, to be exact:

… It occurs within an hour of lunar perigee, and this perigee is the closest one for the entire year.

Of course, there are nutcases out there predicting all kinds of bad stuff, including earthquakes, tsunamis and volcanic eruptions.

After what happened in Japan last week, we don't need any more of that.
