Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 18 September 2026 at 20:44.

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 ♑ Capricorn

Moon is leaving the last ∠3° of ♑ Capricorn tropical zodiac sector and will enter ♒ Aquarius later.

Apparent angular diameter ∠1779"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1779" and ∠1911".

Harvest Moon after 5 days

Next Full Moon is the Harvest Moon of September 2026 after 5 days on 26 September 2026 at 16:49.

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 330 / 1283

The Moon is 10 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 330 of Meeus index or 1283 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.52 days

The length of the lunation is 29 days, 12 hours and 23 minutes. It is 2 hours and 49 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 21 minutes shorter than the mean synodic month length. It is 5 hours and 48 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠61.3°

At the beginning of the lunation cycle the true anomaly is ∠61.3°. At the beginning of next synodic month the true anomaly is going to be ∠94.5°.

Moon after apogee

2 days after point of apogee on 19 September 2026 at 03:00 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 1 October 2026 at 20:41 in ♊ Gemini.

Previous apogeeNext perigee

Distance to Moon 402 890 km

The Moon is 402 890 km (250 344 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 369 338 km (229 496 mi).

Moon before ascending node

11 days after descending node on 9 September 2026 at 19:17 in ♌ Leo. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 24 September 2026 at 02:40 in ♒ Aquarius.

Previous nodeNext node

Draconic month

24 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 after southern standstill

2 days since the previous standstill on 18 September 2026 at 18:54 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.065°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠27.989° at the point of next northern standstill on 2 October 2026 at 11:35 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 26 September 2026 at 16:49 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.
