The Moon will reach full phase. At this time in its monthly cycle of phases, the Moon lies almost directly opposite the Sun in the sky, placing it high above the horizon for much of the night.

The sequence of full moons through the year are often assigned names according to the seasons in which they fall. This month's will be the third to fall in winter 2193 – the Lenten Moon.

Over the nights following 17 March, the Moon will rise around an hour later each day, becoming prominent later in the night. Within a few days, it will only be visible in the pre-dawn and early-morning sky. By the time it reaches last quarter, a week after full moon, it will rise at around midnight and set at around noon.

At the exact moment when the Moon reaches full phase, it will lie at a declination of +01°09' in the constellation Virgo , and so will appear high in the sky at all but the most extreme latitudes. It will be visible at all latitudes between 81°N and 78°S. Its distance from the Earth will be 403,000 km.

The exact position of the Moon at the time it reaches full phase will be:

Object Right Ascension Declination Constellation Angular Size
The Moon 11h40m40s +01°09' Virgo 29'36"

The coordinates above are given in J2000.0.
