The finest time span to observe the supermoon is right after the moonrise and just before the sunrise, but the moon will stun throughout its voyage across the sky. If you want to celebrate the year's most super supermoon as a holiday for moongazers, I don't see anything wrong with that. Early forecasts predict evening showers so hopefully the skies will clear up enough to view the Supermoon. "It's a slightly bigger moon; I ain't using the adjective 'supermoon'".
A new moon is the first phase in the lunar cycle that occurs when the moon is in conjunction with the sun - but is not visible from Earth.
Supermoons happen when the sun, moon and earth align and a full or new moon aligns with the sun's lunar orb. "Nearby perigee full moons appear about 14 percent bigger and 30 percent brighter than full moons that occur near apogee in the moon's orbit".
The only supermoon of the year is slated for December 3, 2017, at precisely 15:47 UTC, according to EarthSky.org. At its perigee, the moon will be just 222,135 miles from Earth, almost 16,000 miles closer than it normally is throughout the year, according to NASA. The moon will become full on Sunday and the best time to see it, if you're awake, will be 3:45 a.m. Monday. And get ready for a total lunar eclipse on January 31.
There is an option offered by the Italian-based Virtual Telescope Project, which consists of several robotic telescopes remotely accessible in real-time over the Internet.
A Blue Moon can be a supermoon, just like any other full moon. But any time you catch a full Moon as it rises or sets, while it's suspended low on the horizon beaming through the silhouettes of trees or buildings, its apparent size might make you do a double-take.
