Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♍ Virgo

Moon is passing about ∠17° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1950".

Wolf Moon after 23 days

Next Full Moon is the Wolf Moon of January 2020 after 23 days on 10 January 2020 at 19:21.

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 246 / 1199

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 246 of Meeus index or 1199 from Brown series.

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 8 minutes. It is 2 hours 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 longer than mean

The length of the current synodic month is 1 hour and 23 minutes longer than the mean synodic month length. It is 5 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠50.7°

At the beginning of the lunation cycle the true anomaly is ∠50.7°. At the beginning of next synodic month the true anomaly is going to be ∠82.6°.

Moon at perigee

Moon is at perigee at 20:30. It is 13 days after previous apogee on 5 December 2019 at 04:09 in ♓ Pisces. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 14 days, until point of next apogee on 2 January 2020 at 01:30 in ♓ Pisces.

Distance to Moon 370 260 km

This perigee Moon is 370 260 km (230 069 mi) away from Earth. This is the year's farthest perigee of 2019. It is 7 752 km closer than the mean perigee distance, but it is still 96 km further than the closest perigee of 21st century.

Moon after ascending node

4 days after ascending node on 13 December 2019 at 14:15 in ♋ Cancer. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 26 December 2019 at 13:01 in ♑ Capricorn.

Draconic month

4 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

4 days since the previous standstill on 13 December 2019 at 20:57 in ♋ Cancer when the Moon has reached North declination of ∠23.226°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-23.227° at the point of next southern standstill on 26 December 2019 at 20:11 in ♑ Capricorn.

Syzygy in 7 days

In 7 days on 26 December 2019 at 05:13 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.
