a blue moon occurs every two or three years. even rarer is a blue moon on new year's eve, which only happens approximately every 20 years. a rare event indeed! the last new year's eve blue moon was in 1990 and the next one, following 2009, won't be until 2028.
i'm so glad i had the chance to look up at midnight on new year's eve and get an eyeful of this rare occurrance. of course i was armed with my camera and captured it. look!
upcoming blue moon dates are now foreseen for august 2012 and july 2015. see you soon, bella!
