Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♋ Cancer

Moon is passing about ∠11° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1785"

Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1785" and ∠1916".

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2021 after 21 days on 20 October 2021 at 14:57.

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 268 / 1221

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 268 of Meeus index or 1221 from Brown series.

Synodic month length 29.43 days

The length of the lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠297.8°

At the beginning of the lunation cycle the true anomaly is ∠297.8°. At the beginning of next synodic month the true anomaly is going to be ∠323.3°.

Moon after apogee

2 days after point of apogee on 26 September 2021 at 21:44 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 8 October 2021 at 17:28 in ♏ Scorpio.

Distance to Moon 401 641 km

The Moon is 401 641 km (249 568 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 363 388 km (225 799 mi).

Moon after ascending node

3 days after ascending node on 26 September 2021 at 07:33 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 9 October 2021 at 19:35 in ♏ Scorpio.

Moon at northern standstill

At 08:26 the Moon is meeting its standstill point to reach North declination of ∠26.109°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-26.204° at the point of next standstill in ♑ Capricorn on 12 October 2021 at 09:09.

Syzygy in 6 days

In 6 days on 6 October 2021 at 11:05 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
