Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 13 October 2019 at 21:08.

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 ♊ Gemini

Moon is passing about ∠5° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1845"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1845" and ∠1926".

Hunter Moon before 3 days

Next Full Moon is the Beaver Moon of November 2019 after 26 days on 12 November 2019 at 13:34.

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 244 / 1197

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 244 of Meeus index or 1197 from Brown series.

PreviousCurrent lunationNext

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 after apogee

6 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 8 days, until the Moon reaches the point of next perigee on 26 October 2019 at 10:41 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 388 456 km

The Moon is 388 456 km (241 375 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 361 316 km (224 511 mi).

Moon before ascending node

11 days after descending node on 5 October 2019 at 18:49 in ♑ Capricorn. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 20 October 2019 at 07:28 in ♋ Cancer.

Draconic month

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

Moon before northern standstill

11 days since the previous standstill on 5 October 2019 at 16:01 in ♑ Capricorn when the Moon has reached South declination of ∠-22.788°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠22.947° at the point of next northern standstill on 20 October 2019 at 08:07 in ♋ Cancer.

Syzygy in 10 days

In 10 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.
