We've just come through the first 8 months of 2012 laden with astrological events. First, there was the string of retrogrades – Mars, then Venus, punctuated by Mercury retrograde in Leo. The retrograde energy only just lifted around August 22nd, as Mercury emerged from its post-retro shadow. We also had a summer rife with some rather momentous events – the first exact Uranus-Pluto square in June, the eclipses of late May and early June, the Venus-transit-across-the-Sun in June, AND the "Cardinal Cross" lineup of Mars in Libra, Uranus in Aries, the Sun in Cancer, and the Moon and Pluto in Capricorn in early July.
On August 31, 2012 we have the second Full Moon in a month, sometimes known as a Blue Moon. Is it really a Blue Moon? That's the $64,000 question of the day! The original definition of a Blue Moon was that it was the third of four Full Moons within a season. Typically a season (calculated from equinox to solstice or vice versa) has three Full Moons and several religous holidays or other festivals were based on the timing of Full Moons. So when a season had four Full Moons, this threw off the count and interferred with the correct timing for a holiday. The third Full Moon of the Season was considered to be the "extra" one or the Blue Moon, because there are names for the first, second and last Full Moon of each season. So the extra one was known as the Blue Moon.
Today's Full Moon is an odd one. It's the second Full Moon in a month, but it's NOT the third of four Full Moons in a season. The next Full Moon is on September 29th, after the Fall Equinox on September 22nd. So according to the original definition of a Blue Moon, this is NOT one! In fact the next REAL Blue Moon will be on August 21, 2013, but keep reading, and you'll be vindicated.
