Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 6 January 2021 at 09:37.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♐ Sagittarius

Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1953"

Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1953" and ∠1951".

Wolf Moon after 18 days

Next Full Moon is the Wolf Moon of January 2021 after 18 days on 28 January 2021 at 19:16.

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 259 / 1212

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.53 days

The length of the lunation is 29 days, 12 hours and 44 minutes. It is 1 hour and 21 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit position on

True anomaly ∠30.1°

At the beginning of the lunation cycle the true anomaly is ∠30.1°. At the beginning of next synodic month the true anomaly is going to be ∠53.8°.

Moon after perigee

1 day after point of perigee on 9 January 2021 at 15:39 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next apogee on 21 January 2021 at 13:11 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 366 991 km

The Moon is 366 991 km (228 038 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 361 km (251 258 mi).

Moon in descending node

Moon is in descending node in ♐ Sagittarius at 20:15 crossing the ecliptic from North to South to meet ascending node 14 days later on 24 January 2021 at 21:47 in ♊ Gemini.

Draconic month

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

Moon before southern standstill

11 days since the previous standstill on 30 December 2020 at 07:53 in ♋ Cancer when the Moon has reached North declination of ∠24.868°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-24.870° at the point of next southern standstill on 12 January 2021 at 08:18 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 2 days

In 2 days on 13 January 2021 at 05:00 in ♑ Capricorn 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.
