Tonight we will have a full moon. But it's not just any full moon. The full moon has two special characteristics. It's technically happening just after midnight - on Friday the 13th. The full moon is also what astronomers call a Super Moon.. The full moon on Friday the 13th is a rarity. According to David DeBruyn, emeritus director for the Chaffee Planetarium in Grand Rapids, a full moon on Friday the 13th hasn't happened since October 2000. He also says the next full moon on Friday the 13th won't occur until August 2049.
A full moon is often thought of as an event of a full night's duration. This is somewhat misleading because the Moon seen from Earth is continuously becoming larger and/or smaller (though much too slowly to notice with the naked eye). Its absolute maximum size occurs at the moment expansion has stopped.
