Not just once if it’s a ‘blue’ moon-A A +A
Saturday, September 1, 2012
A BLUE moon like what we had last night is not an extraordinary planetary event but just the occurrence of a second full moon within one month, said a Cebuano astro-photographer.
“A lunar month is 29 and a half days, so it is rare in lunar months to have a second full moon,” Christopher Go said in a phone interview.
“It occurs at least once every two years,” he said.
Every month except February has at least 30 days so the potential for the occurrence of two full moons in a month isn’t that unusual.
Neither is the moon blue. A post on the United States National Aeronautics and Space Administration (NASA) website states that a “blue moon” is really “pale gray and white, indistinguishable from any other moon you’ve ever seen.”
