Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♋ Cancer

Moon is passing about ∠12° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1812"

Lunar disc appears visually 6.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1812" and ∠1925".

Worm Moon after 6 days

Next Full Moon is the Worm Moon of March 2021 after 6 days on 28 March 2021 at 18:48.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 262 / 1215

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 262 of Meeus index or 1215 from Brown series.

Synodic month length 29.67 days

The length of the lunation is 29 days, 16 hours and 10 minutes. It is 19 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 3 hours and 26 minutes longer than the mean synodic month length. It is 3 hours and 37 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠124.3°

At the beginning of the lunation cycle the true anomaly is ∠124.3°. At the beginning of next synodic month the true anomaly is going to be ∠154.8°.

Moon after apogee

4 days after point of apogee on 18 March 2021 at 05:04 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 30 March 2021 at 06:12 in ♏ Scorpio.

Distance to Moon 395 676 km

The Moon is 395 676 km (245 862 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 360 311 km (223 887 mi).

Moon after ascending node

2 days after ascending node on 20 March 2021 at 03:31 in ♊ Gemini. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 2 April 2021 at 02:41 in ♐ Sagittarius.

Draconic month

2 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the beginning to the first part of the cycle.

Moon at northern standstill

At 08:35 the Moon is meeting its standstill point to reach North declination of ∠25.307°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-25.412° at the point of next standstill in ♑ Capricorn on 4 April 2021 at 02:08.

Syzygy in 6 days

In 6 days on 28 March 2021 at 18:48 in ♎ Libra the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
