2017 Apr 11

The Moon will reach full phase – making it visible for much of the night, lying almost directly opposite the Sun in the sky.

Full Moons are traditionally given names according to the season in which they fall, and this will be the first full moon of spring 2017, traditionally called the Egg Moon.

Over the nights following 11 April, the Moon will rise around an hour later each day so as to become 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 moment when the Moon reaches full phase, it will lie at a declination of -04°43' 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 75°N and 84°S. Its distance from the Earth will be 398,000 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 13h24m30s -04°43' Virgo 29'57"

The coordinates above are given in J2000.0.
