Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 30 December 2020 at 03:28.

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 ♍ Virgo

Moon is passing about ∠20° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1938"

Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1951".

Cold Moon before 5 days

Next Full Moon is the Wolf Moon of January 2021 after 24 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 20 days old. Earth's natural satellite is moving from the middle to the last 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 before apogee

10 days after point of apogee on 24 December 2020 at 16:32 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 9 January 2021 at 15:39 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 369 862 km

The Moon is 369 862 km (229 822 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 367 390 km (228 286 mi).

Moon before descending node

6 days after ascending node on 28 December 2020 at 15:03 in ♊ Gemini. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 10 January 2021 at 20:15 in ♐ Sagittarius.

Draconic month

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

Moon after northern standstill

5 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 7 days 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 8 days

In 8 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.
