Last Quarter in Taurus

Last Quarter on . Illuminated surface of the Moon is 54% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 27 July 2054 at 21:28 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 is entering ♉ Taurus

Moon is passing first ∠0° of ♉ Taurus tropical zodiac sector.

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2054 after 21 days on 18 August 2054 at 09:22.

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 ∠1829"

Lunar disc appears visually 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1829" and ∠1890".

Lunation 674 / 1627

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 674 of Meeus index or 1627 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 14 minutes and it is 16 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2054. 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 shorter than mean

The length of the current synodic month is 5 hours and 30 minutes shorter than the mean synodic month length. It is 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠336°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠336° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠352.3°.

Moon after apogee

5 days since point of apogee on 22 July 2054 at 05:49 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 4 August 2054 at 04:47 in ♌ Leo.

Distance to Moon 391 868 km

The Moon is 391 868 km (243 495 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 668 km (222 245 mi).

Moon after descending node

5 days after descending node on 22 July 2054 at 09:02 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 August 2054 at 20:23 in ♌ Leo.

Moon before northern standstill

9 days since the last southern standstill on 18 July 2054 at 03:03 in ♑ Capricorn when the Moon has reached South declination of ∠-19.176° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠19.139° at the point of next northern standstill on 1 August 2054 at 11:52 in ♋ Cancer.

Draconic month

19 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 3 August 2054 at 17:48 in ♌ Leo 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.
