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.

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

Upcoming main Moon phases

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.

Synodic month length 29.79 days

Length of current 878 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 next lunation 879 length.

Lunation length longer than mean

Length of current synodic month is 6 hours and 16 minutes longer than the mean length of synodic month, but it is still 47 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠187.9°

This lunation true anomaly is ∠187.9°. At the beginning of next synodic month true anomaly will be ∠214.7°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after perigee

6 days after point of perigee on 15 January 2071 at 08:40 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 27 January 2071 at 21:04 in ♐ Sagittarius.

Distance to Moon 386 040 km

Moon is 386 040 km (239 874 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 406 168 km (252 381 mi).

Moon in ascending node

New draconic month

At 06:04 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

7 days after previous North standstill on 14 January 2071 at 05:41 in ♊ Gemini, when Moon has reached northern declination of ∠18.487°. Next 6 days the lunar orbit moves southward to face South declination of ∠-18.432° in the next southern standstill on 27 January 2071 at 15:29 in ♐ Sagittarius.

Syzygy in 9 days

After 9 days on 31 January 2071 at 07:16 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
