Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 29 January 2040 at 07:54.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♎ Libra

Moon is leaving the last ∠3° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Apparent angular diameter ∠1909"

Lunar disc appears visually 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1909" and ∠1946".

Wolf Moon before 6 days

Next Full Moon is the Snow Moon of February 2040 after 23 days on 28 February 2040 at 00:59.

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 495 / 1448

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 495 of Meeus index or 1448 from Brown series.

Synodic month length 29.46 days

The length of the lunation is 29 days, 10 hours and 59 minutes. This is the year's shortest synodic month of 2040. It is 23 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 1 hour and 45 minutes shorter than the mean synodic month length. It is 4 hours and 24 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠12.4°

At the beginning of the lunation cycle the true anomaly is ∠12.4°. At the beginning of next synodic month the true anomaly is going to be ∠30.1°.

Moon before apogee

9 days after point of apogee on 25 January 2040 at 22:42 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 10 February 2040 at 18:42 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 375 497 km

The Moon is 375 497 km (233 323 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 361 749 km (224 780 mi).

Moon before descending node

10 days after ascending node on 24 January 2040 at 12:28 in ♊ Gemini. The Moon is located north of the ecliptic over the following 3 days, until the lunar orbit crosses from North to South in descending node on 7 February 2040 at 15:18 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

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

Moon before southern standstill

8 days since the previous standstill on 26 January 2040 at 22:14 in ♋ Cancer when the Moon has reached North declination of ∠25.480°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-25.560° at the point of next southern standstill on 9 February 2040 at 16:13 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 8 days

In 8 days on 12 February 2040 at 14:24 in ♒ Aquarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
