Moon phase and lunation details

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 28 October 2021 at 20:05.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♍ Virgo

Moon is passing about ∠10° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1869"

Lunar disc appears visually 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1869" and ∠1933".

Beaver Moon after 18 days

Next Full Moon is the Beaver Moon of November 2021 after 18 days on 19 November 2021 at 08:58.

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 269 / 1222

The Moon is 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.

Synodic month length 29.42 days

The length of the lunation is 29 days, 10 hours and 9 minutes. This is the year's shortest synodic month of 2021. It is 19 minutes shorter 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 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠323.3°

At the beginning of the lunation cycle the true anomaly is ∠323.3°. At the beginning of next synodic month the true anomaly is going to be ∠342.3°.

Moon before apogee

6 days after point of apogee on 24 October 2021 at 15:30 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 5 November 2021 at 22:23 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 383 592 km

The Moon is 383 592 km (238 353 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 845 km (222 976 mi).

Moon before descending node

8 days after ascending node on 23 October 2021 at 11:47 in ♊ Gemini. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.

Draconic month

8 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 after northern standstill

4 days since the previous standstill on 26 October 2021 at 16:04 in ♋ Cancer when the Moon has reached North declination of ∠26.291°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-26.328° at the point of next southern standstill on 8 November 2021 at 16:27 in ♑ Capricorn.

Syzygy in 4 days

In 4 days on 4 November 2021 at 21:15 in ♏ Scorpio 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.
