Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 15 October 2027 at 13:47.

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 is entering ♊ Gemini

Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1899"

Lunar disc appears visually 1.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1899" and ∠1926".

Hunter Moon before 2 days

Next Full Moon is the Beaver Moon of November 2027 after 26 days on 14 November 2027 at 03:26.

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 343 / 1296

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 343 of Meeus index or 1296 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.46 days

The length of the lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 48 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 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠36.7°

At the beginning of the lunation cycle the true anomaly is ∠36.7°. At the beginning of next synodic month the true anomaly is going to be ∠61.7°.

Moon before apogee

8 days after point of apogee on 9 October 2027 at 15:47 in ♒ Aquarius. 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 25 October 2027 at 05:36 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 377 490 km

The Moon is 377 490 km (234 561 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 368 651 km (229 069 mi).

Moon before descending node

8 days after ascending node on 9 October 2027 at 14:58 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 23 October 2027 at 08:15 in ♌ Leo.

Draconic month

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

Moon before northern standstill

12 days since the previous standstill on 5 October 2027 at 16:53 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.921°, the lunar orbit is extending northward over the next day to face maximum declination of ∠26.793° at the point of next northern standstill on 20 October 2027 at 01:41 in ♊ Gemini.

Syzygy in 11 days

In 11 days on 29 October 2027 at 13:36 in ♎ Libra 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.
