The moon appears full to the eye for two to three nights. However, astronomers regard the moon as full at a precisely defined instant, when the moon is exactly 180 degrees opposite the sun in ecliptic longitude. That full moon instant comes in the early morning hours Tuesday, November 12, 2019, according to clocks in the Americas (8:34 a.m. Eastern on November 12, or 13:34 UTC; translate UTC to your time).

Sometimes the November full moon is the Hunter’s Moon, but not this year. By tradition, the Harvest Moon is the full moon closest to the September equinox. This year’s Harvest Moon came early, on September 13, 2019. Also by tradition, the Hunter’s Moon is the full moon following the Harvest Moon. So this year’s Hunter’s Moon was the full moon of October 12-13.

Never fear, though. November’s full moon has names all its own. The full moon of November is called the Frosty Moon or Beaver Moon.

This full moon will interfere with the peak of the North Taurid meteor shower. It comes as the moon is sweeping through the constellation Taurus the Bull, the same constellation from which the North Taurid meteors radiate.

Why does a full moon look full? Remember that half the moon is always illuminated by the sun. That lighted half is the moon’s day side. In order to appear full to us on Earth, we have to see the entire day side of the moon. That happens only when the moon is opposite the sun in our sky. So a full moon looks full because it’s opposite the sun.

That’s also why every full moon rises in the east around sunset – climbs highest up for the night midway between sunset and sunrise (around midnight) – and sets around sunrise. Stand outside tonight around sunset and look for the moon. Sun going down while the moon is coming up? That’s a full moon, or close to one.

Just be aware that the moon will look full for at least a couple of night around the instant of full moon.

Often, you’ll find two different dates on calendars for the date of full moon. That’s because some calendars list moon phases in Coordinated Universal Time, also called Universal Time Coordinated (UTC). And other calendars list moon phases in local time, a clock time of a specific place, usually the place that made and distributed the calendars. Translate UTC to your local time.

If a full moon is opposite the sun, why doesn’t Earth’s shadow fall on the moon at every full moon? The reason is that the moon’s orbit is titled by 5.1 degrees with respect to Earth’s orbit around the sun. At every full moon, Earth’s shadow sweeps near the moon. But, in most months, there’s no eclipse.

As the moon orbits Earth, it changes phase in an orderly way. Follow these links to understand the various phases of the moon.

Bottom line: Full moon – when the moon is most opposite the sun for this month – falls on Tuesday, November 12, 2019, according to clocks in the Americas (8:34 a.m. Eastern on November 12, or 13:34 UTC; translate UTC to your time).
