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 ♋ Cancer

Moon is leaving the last ∠3° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1935"

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1935" and ∠1928".

Next Full Moon is the Beaver Moon of November 2019 after 22 days on 12 November 2019 at 13:34.

Synodic month length 29.38 days

The length of the lunation is 29 days, 9 hours and 12 minutes. It is 2 hours and 15 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 3 hours and 32 minutes shorter than the mean synodic month length. It is 2 hours and 37 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠11.4°

At the beginning of the lunation cycle the true anomaly is ∠11.4°. At the beginning of next synodic month the true anomaly is going to be ∠28.3°.

Moon before apogee

10 days after point of apogee on 10 October 2019 at 18:29 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 26 October 2019 at 10:41 in ♎ Libra.

Distance to Moon 370 455 km

The Moon is 370 455 km (230 190 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 361 316 km (224 511 mi).

Moon after ascending node

1 day after ascending node on 20 October 2019 at 07:28 in ♋ Cancer. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 1 November 2019 at 21:40 in ♑ Capricorn.

Draconic month

1 day 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

1 day since the previous standstill on 20 October 2019 at 08:07 in ♋ Cancer when the Moon has reached North declination of ∠22.947°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-23.047° at the point of next southern standstill on 2 November 2019 at 00:33 in ♑ Capricorn.

Syzygy in 6 days

In 6 days on 28 October 2019 at 03:38 in ♏ Scorpio 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.
