OLD-FASHIONED BLUE MOON: According to modern folklore, a Blue Moon is the second full Moon in a calendar month. The next Blue Moon to fit this description will come on August 31, 2012. Do we really have to wait so long? There is an older definition that says the next Blue Moon is this weekend. To prepare for the event, Stefano De Rosa snapped this picture of the Moon waxing full over Turin, Italy:
The Moon is full on Nov. 21st. Usually there are only three full Moons in a season, but this Fall there will be four. The full Moon of Nov. 21st is the third of those four. According to old editions of the Maine Farmer’s Almanac, that makes it a Blue Moon. Confused? No wonder the modern definition is so much simpler.
"We have bad weather forecast for the 21st," says De Rosa, "so I took my old-fashioned Blue Moon photo on the 19th instead. It might not be truly blue, but the Moon looked great anyway rising alongside the Superga church while another wonder from the sky was joining the scene!"
Readers, be alert on Sunday night for a Blue Moon of your own.
