This will be the last blue moon until 2020, so don't miss it. Since the last full moon fell on March 1st, tonight's full moon on March 31st is considered a "blue moon". Unusually, this is the second blue moon to occur this year, with the first one falling on January 31st when there was a Super Blue Blood Moon. In addition to tonight's blue moon, it will also be a "Paschal" moon.
