December 3, 2017 Supermoon

Over thirty years ago astrologer Richard Nolle coined the term Supermoon, he defined it as –

… a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit.

Once each month the Moon is full (opposite Earth from the Sun), once a month new (between Earth and the Sun). The closest point of orbit is called perigee, farthest point, apogee. By definition Supermoon occurs at perigee, this happens 4 – 6 times a year. All perigee moons are Supermoons, not all Supermoons are full moons. On December 3 the first and only full supermoon of 2017 happens worldwide at 15:47 UTC. (Translate to your time zone at – http://earthsky.org/astronomy-essentials/universal-time )

Poor weather needn’t squelch inclination to howl at the super wolf moon. Linked below, the Virtual Telescope Project in Rome, access to remote robotic telescopes and live streaming of astronomical events.

  1. We always seemed to have such bad luck observing celestial events when we were on the road; either overcast or we were in places where we couldn’t get a sightline to the event. Am looking forward to better luck here — even with the lights of the city.
