The moon reaches the full phase tomorrow morning at 7:19 a.m. Central Time. Tonight’s bright lunar orb is closest to the time when it stands opposite the sun. Regardless of the calendar date, the moon appears full during the next few nights.

This full moon is known as the Beaver Moon, the second of the autumn season. It signals the approach of winter, with frosts and early snows settling across northern regions. Beavers begin reinforcing their dams before the freeze sets in.

Perigee (Super) Moon

At this full phase, the moon is near perigee—its closest point to Earth—occurring tomorrow at 4:27 p.m. Central Time. The lunar orb appears slightly larger and brighter than average, sometimes referred to as a supermoon, a Super Beaver Moon

An hour after sunset, the bright moon shines about 20° above the eastern horizon, in front of Aries. It is 7.5° to the lower right of Hamal, the constellation’s brightest star. A binocular helps reveal the star through the moonlight.

At this time, Saturn is nearly 30° up in the southeast—one-third of the way from the horizon to overhead—and about 40° to the moon’s upper right. The Ringed Wonder currently shows its rings from the edge, reflecting much of their light away from Earth, making the planet appear dimmer than usual.

As the night progresses, both the moon and Saturn move westward. Saturn reaches the southern sky and its highest point about two hours after sunset, then sets a few hours after midnight. The moon is south before midnight and sets tomorrow morning near sunrise.

Watch for the bright Beaver Moon lighting up the sky during the next few evenings.
