Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 7 September 2027 at 18:31.

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 ♒ Aquarius

Moon is passing about ∠11° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1907".

Harvest Moon after 3 days

Next Full Moon is the Harvest Moon of September 2027 after 3 days on 15 September 2027 at 23:04.

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 342 / 1295

The Moon is 11 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 342 of Meeus index or 1295 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 55 minutes. It is 2 hours and 5 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 shorter than mean

The length of the current synodic month is 3 hours and 49 minutes shorter than the mean synodic month length. It is 2 hours and 20 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠18.2°

At the beginning of the lunation cycle the true anomaly is ∠18.2°. At the beginning of next synodic month the true anomaly is going to be ∠36.7°.

Moon after apogee

1 day after point of apogee on 11 September 2027 at 23:39 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 15 days, until the Moon reaches the point of next perigee on 27 September 2027 at 20:12 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 405 491 km

The Moon is 405 491 km (251 960 mi) away from Earth and getting closer over the next 15 days until the point perigee when Earth-Moon distance is going to be 363 455 km (225 840 mi).

Moon in ascending node

Moon is in ascending node in ♒ Aquarius at 11:26 crossing the ecliptic from South to North to meet descending node 13 days later on 26 September 2027 at 06:04 in ♌ Leo.

Previous nodeNext node

New draconic month

At 11:26 the Moon completes the previous draconic month and enters the new one.

Moon after southern standstill

4 days since the previous standstill on 8 September 2027 at 08:57 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.122°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠27.015° at the point of next northern standstill on 22 September 2027 at 20:33 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 3 days

In 3 days on 15 September 2027 at 23:04 in ♓ Pisces 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.
