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 is entering ♐ Sagittarius

Moon is passing first ∠3° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1824"

Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1893".

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2027 after 6 days on 17 August 2027 at 07:29.

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 341 / 1294

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 341 of Meeus index or 1294 from Brown series.

Synodic month length 29.32 days

The length of the lunation is 29 days, 7 hours and 36 minutes. It is 1 hour and 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 shorter than mean

The length of the current synodic month is 5 hours and 8 minutes shorter than the mean synodic month length. It is 1 hour and 1 minute longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠2.6°

At the beginning of the lunation cycle the true anomaly is ∠2.6°. At the beginning of next synodic month the true anomaly is going to be ∠18.2°.

Moon before perigee

8 days after point of perigee on 2 August 2027 at 06:28 in ♌ Leo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 15 August 2027 at 14:23 in ♑ Capricorn.

Distance to Moon 392 954 km

The Moon is 392 954 km (244 170 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 086 km (252 330 mi).

Moon before ascending node

7 days after descending node on 2 August 2027 at 12:33 in ♌ Leo. 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 16 August 2027 at 05:51 in ♒ Aquarius.

Draconic month

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

Moon before southern standstill

11 days since the previous standstill on 30 July 2027 at 05:47 in ♊ Gemini when the Moon has reached North declination of ∠27.208°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-27.209° at the point of next southern standstill on 12 August 2027 at 02:05 in ♐ Sagittarius.

Syzygy in 6 days

In 6 days on 17 August 2027 at 07:29 in ♒ Aquarius 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.
