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 )
December’s full moon is known as the long night or wolf moon in native American folklore. Ponder all things moon courtesy Eartsky astronomy essentials at – http://earthsky.org/astronomy-essentials/full-moon-names
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.
Moving in an ellipse around Earth, the Moon completes one orbit a month. Once a month the Moon is full, or opposite Earth. Once each month a new moon rises at a point between Earth and the Sun. At closest orbital position to Earth a Moon is called perigee, farthest away is an apogee Moon.When full moons coincide with perigee, a Supermoon is born. At perigee the Moon is 50,000 Km closer to Earth than at apogee.
Supermoon used to be known as full perigee moon. 30 years ago astrologer Richard Nolle coined the phrase and it stuck. On Monday November 14 the Moon becomes full 2 hours away from perigee, a circumstance not witnessed since January 28, 1948 and not duplicated until November 25, 2034. Best seats for supermoon’s 14% larger, 30% brighter show should be secured at Moon rise or set, time-frames when “Moon Illusion” is star of the show.
Moon illusion is an optical illusion – ponder http://www.mnn.com/earth-matters/space/blogs/why-nobody-can-explain-the-moon-illusion
Understanding optical trickery satisfies the curious, supermoon illusion tickles the soul. No other illusion stirs inexplicable wonder, smacks consciousness without warning or possesses the power to stop witnesses in their track. Watch Full Moon Silhouettes below, it’s breathtaking.
