Last Quarter in Scorpio

Last Quarter on . The illuminated surface of the moon is 55% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 14 February 2031 at 22:50 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♏ Scorpio

Moon is passing about ∠20° of ♏ Scorpio tropical zodiac sector.

Worm Moon after 22 days

Next Full Moon is the Worm Moon of March 2031 after 22 days on 9 March 2031 at 04:30.

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.

Apparent angular diameter ∠1949"

Lunar disc appears visually 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1949" and ∠1943".

Lunation 384 / 1337

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 384 of Meeus index or 1337 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 18 minutes and it is 42 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 26 minutes shorter than the mean synodic month length. It is 4 hours and 43 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠21.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠21.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠41.9°.

Moon before perigee

11 days since point of apogee on 2 February 2031 at 23:45 in ♊ Gemini 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 19 February 2031 at 00:35 in ♒ Aquarius.

Distance to Moon 367 788 km

The Moon is 367 788 km (228 533 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 364 745 km (226 642 mi).

Moon before ascending node

13 days after descending node on 1 February 2031 at 09:25 in ♊ Gemini the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 15 February 2031 at 11:21 in ♐ Sagittarius.

Moon before southern standstill

11 days since the last northern standstill on 2 February 2031 at 12:52 in ♊ Gemini when the Moon has reached North declination of ∠21.745° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-21.615° at the point of next southern standstill on 16 February 2031 at 13:25 in ♐ Sagittarius.

Draconic month

26 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 21 February 2031 at 15:49 in ♒ Aquarius 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.
