Don't miss a bright lunar disk and countdown to the next supermoon events. Supermoon: A supermoon is a new or full moon (syzygy) which occurs when the Moon is at 90% or greater of its mean closest approach to Earth (perigee). Therefore you can called it a perigee-syzygy event. During a super full moon the lunar disk appears brighter and bigger than usual. Features: - show only super full, only super new or both super moon events - add supermoon events to your calendar - share event dates via e-mail, Twitter or Facebook © © 2013 Piet Jonas |
