Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 16 January 2071 at 02:35.

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 passing about ∠13° of ♎ Libra tropical zodiac sector.

Apparent angular diameter ∠1857"

Lunar disc appears visually 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1857" and ∠1950".

Wolf Moon before 5 days

Next Full Moon is the Snow Moon of February 2071 after 24 days on 14 February 2071 at 13:33.

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 878 / 1831

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 878 of Meeus index or 1831 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.79 days

The length of the lunation is 29 days, 19 hours and 1 minute. This is the year's longest synodic month of 2071. It is 1 hour and 44 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 6 hours and 16 minutes longer than the mean synodic month length. It is 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠187.9°

At the beginning of the lunation cycle the true anomaly is ∠187.9°. At the beginning of next synodic month the true anomaly is going to be ∠214.7°.

Moon after perigee

6 days after point of perigee on 15 January 2071 at 08:40 in ♋ Cancer. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next apogee on 27 January 2071 at 21:04 in ♐ Sagittarius.

Previous perigeeNext apogee

Distance to Moon 386 040 km

The Moon is 386 040 km (239 874 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 168 km (252 381 mi).

Moon in ascending node

Moon is in ascending node in ♎ Libra at 06:04 crossing the ecliptic from South to North to meet descending node 14 days later on 4 February 2071 at 20:30 in ♈ Aries.

New draconic month

At 06:04 the Moon completes the previous draconic month and enters the new one.

Moon before southern standstill

7 days since the previous standstill on 14 January 2071 at 05:41 in ♊ Gemini when the Moon has reached North declination of ∠18.487°, the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.432° at the point of next southern standstill on 27 January 2071 at 15:29 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 9 days

In 9 days on 31 January 2071 at 07:16 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.
