Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 13 October 2021 at 03:25.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♓ Pisces

Moon is passing about ∠18° of ♓ Pisces tropical zodiac sector.

Apparent angular diameter ∠1854"

Lunar disc appears visually 3.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1854" and ∠1926".

Hunter Moon after 3 days

Next Full Moon is the Hunter Moon of October 2021 after 3 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 269 / 1222

The Moon is 12 days young. Earth's natural satellite is moving from the first to the middle 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 perigee

8 days after point of perigee on 8 October 2021 at 17:28 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next apogee on 24 October 2021 at 15:30 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 386 576 km

The Moon is 386 576 km (240 207 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 616 km (252 038 mi).

Moon before ascending node

7 days after descending node on 9 October 2021 at 19:35 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 5 days, until the lunar orbit crosses from South to North in ascending node on 23 October 2021 at 11:47 in ♊ Gemini.

Draconic month

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

Moon after southern standstill

5 days since the previous standstill on 12 October 2021 at 09:09 in ♑ Capricorn when the Moon has reached South declination of ∠-26.204°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠26.291° at the point of next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.

Syzygy in 3 days

In 3 days on 20 October 2021 at 14:57 in ♈ Aries 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.
