Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 22 September 2023 at 19:32.

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 ∠8° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1967"

Lunar disc appears visually 2.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1913".

Harvest Moon after 3 days

Next Full Moon is the Harvest Moon of September 2023 after 3 days on 29 September 2023 at 09:57.

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 293 / 1246

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 293 of Meeus index or 1246 from Brown series.

Synodic month length 29.68 days

The length of the lunation is 29 days, 16 hours and 15 minutes. This is the year's longest synodic month of 2023. It is 43 minutes longer 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 longer than mean

The length of the current synodic month is 3 hours and 31 minutes longer than the mean synodic month length. It is 3 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠202.9°

At the beginning of the lunation cycle the true anomaly is ∠202.9°. At the beginning of next synodic month the true anomaly is going to be ∠232.5°.

Moon before apogee

12 days after point of apogee on 12 September 2023 at 15:42 in ♌ Leo. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 28 September 2023 at 01:05 in ♓ Pisces.

Previous apogeeNext perigee

Distance to Moon 364 486 km

The Moon is 364 486 km (226 481 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 359 911 km (223 638 mi).

Moon before ascending node

7 days after descending node on 17 September 2023 at 19:18 in ♎ Libra. 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 30 September 2023 at 16:49 in ♈ Aries.

Draconic month

22 days since the beginning of current draconic month in ♈ Aries, 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 23 September 2023 at 03:42 in ♑ Capricorn when the Moon has reached South declination of ∠-28.254°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.294° at the point of next northern standstill on 5 October 2023 at 20:31 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 3 days

In 3 days on 29 September 2023 at 09:57 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.
