    Cool Full Moon - Unusually Big & Bright - May 5

    The 2012 May Full Moon will reach its peak during the night of May 5-6. It will be the biggest and brightest since 2006 and until 2018 due to the greatest percentage of disk illumination virtually coinciding with perigee while the Moon hugs close to the ecliptic. The Full Moon’s geocentric angular diameter will be 33.5 arcminutes, and its geocentric brightness factor will be 1.055. See my panorama of fifteen 2012-13 Full Moons for comparisons: www.CurtRenz.com/moon

    A Full Moon is typically twelve times brighter than a Half Moon due to the oppositional flash. That’s caused by direct reflection with minimal shadowing. The upcoming Full Moon will be even brighter. Enjoy the show!

    Photos and descriptions of the May Full Moon would be welcome additions to this thread. Below is my shot of last month’s Full Moon taken from Arlington Heights, Illinois on 2012 APR 06 at 19:49 CDT.

    Well, Swift, thatís a 3% chance of no rain. Better than the probability of winning the lottery! Our Chicago forecast had been looking good, but now they give us a 40% chance for thunderstorms. Letís hope that unlike last night, the Cubs are able to play in Cincinnati tonight.
