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
