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 is entering ♍ Virgo

Moon is passing first ∠4° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1954"

Lunar disc appears visually 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1954" and ∠1947".

Cold Moon after 23 days

Next Full Moon is the Cold Moon of December 2099 after 23 days on 27 December 2099 at 12:58.

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 1235 / 2188

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 1235 of Meeus index or 2188 from Brown series.

Synodic month length 29.49 days

The length of the lunation is 29 days, 11 hours and 40 minutes. It is 2 hours and 7 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 shorter than mean

The length of the current synodic month is 1 hour and 4 minutes shorter than the mean synodic month length. It is 5 hours and 5 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠27.7°

At the beginning of the lunation cycle the true anomaly is ∠27.7°. At the beginning of next synodic month the true anomaly is going to be ∠49.8°.

Moon before apogee

11 days after point of apogee on 22 November 2099 at 17:25 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 8 December 2099 at 17:50 in ♎ Libra.

Distance to Moon 366 856 km

The Moon is 366 856 km (227 954 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 366 610 km (227 801 mi).

Moon before descending node

12 days after ascending node on 21 November 2099 at 23:18 in ♓ Pisces. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 5 December 2099 at 21:04 in ♍ Virgo.

Draconic month

12 days since the beginning of current draconic month in ♓ Pisces, 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 29 November 2099 at 16:41 in ♊ Gemini when the Moon has reached North declination of ∠28.380°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-28.351° at the point of next southern standstill on 12 December 2099 at 13:59 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 11 December 2099 at 23:09 in ♐ Sagittarius 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.
