Moon phase and lunation details

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 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 leaving the last ∠1° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

Apparent angular diameter ∠1936"

Lunar disc appears visually 0.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1936" and ∠1951".

Wolf Moon after 17 days

Next Full Moon is the Wolf Moon of January 2021 after 17 days on 28 January 2021 at 19:16.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 259 / 1212

The Moon is 27 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 10 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 370 266 km

The Moon is 370 266 km (230 073 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 404 361 km (251 258 mi).

Moon after descending node

1 day after descending node on 10 January 2021 at 20:15 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following 13 days, until the lunar orbit crosses from South to North in ascending node on 24 January 2021 at 21:47 in ♊ Gemini.

Draconic month

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

Moon before southern standstill

12 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 1 day

In 1 day 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.
