Last Quarter in Scorpio

Last Quarter on . Illuminated surface of the Moon is 45% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 24 January 2079 at 21:46 UTC.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♏ Scorpio

Moon is passing about ∠12° of ♏ Scorpio tropical zodiac sector.

Snow Moon after 21 days

Next Full Moon is the Snow Moon of February 2079 after 21 days on 15 February 2079 at 23:45.

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 ∠1773"

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1949".

Lunation 977 / 1930

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 977 of Meeus index or 1930 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 45 minutes and it is 2 hours and 32 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 4 hours and 1 minute longer than the mean synodic month length. It is 3 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠225.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠225.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠261.8°.

Moon before apogee

10 days since point of perigee on 15 January 2079 at 03:12 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 26 January 2079 at 21:03 in ♏ Scorpio.

Distance to Moon 404 291 km

The Moon is 404 291 km (251 215 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 718 km (251 480 mi).

Moon after descending node

1 day after descending node on 24 January 2079 at 23:31 in ♎ Libra the Moon is positioned south of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from South to North in ascending node on 7 February 2079 at 23:17 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 16 January 2079 at 00:05 in ♋ Cancer when the Moon has reached North declination of ∠27.561° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-27.617° at the point of next southern standstill on 30 January 2079 at 00:20 in ♑ Capricorn.

Draconic month

13 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 1 February 2079 at 23:35 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.
