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 ♊ Gemini

Moon is leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1915"

Lunar disc appears visually 0.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1906".

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2001 after 21 days on 2 October 2001 at 13:49.

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 20 / 973

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 20 of Meeus index or 973 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 32 minutes. It is 1 hour and 24 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 5 hours and 12 minutes shorter than the mean synodic month length. It is 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠358.1°

At the beginning of the lunation cycle the true anomaly is ∠358.1°. At the beginning of next synodic month the true anomaly is going to be ∠13.2°.

Moon before apogee

9 days after point of apogee on 1 September 2001 at 23:26 in ♒ Aquarius. 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 16 September 2001 at 15:50 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 374 215 km

The Moon is 374 215 km (232 526 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 128 km (222 530 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 21:36 crossing the ecliptic from South to North to meet descending node 12 days later on 24 September 2001 at 10:28 in ♑ Capricorn.

New draconic month

At 21:36 the Moon completes the previous draconic month and enters the new one.

Moon before northern standstill

13 days since the previous standstill on 28 August 2001 at 23:14 in ♑ Capricorn when the Moon has reached South declination of ∠-23.546°, the lunar orbit is extending northward over the next day to face maximum declination of ∠23.677° at the point of next northern standstill on 12 September 2001 at 12:19 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 5 days

In 5 days on 17 September 2001 at 10:27 in ♍ Virgo 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.
