Last Quarter in Aries

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 10 July 2023 at 01:48 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 ♈ Aries

Moon is passing about ∠23° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2023 after 22 days on 1 August 2023 at 18:31.

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 ∠1917"

Lunar disc appears visually 1.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1917" and ∠1887".

Lunation 290 / 1243

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 290 of Meeus index or 1243 from Brown series.

Synodic month length 29.58 days

The length of this lunation is 29 days, 13 hours and 55 minutes and it is 1 hour and 11 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 longer than mean

The length of the current synodic month is 1 hour and 11 minutes longer than the mean synodic month length. It is 5 hours and 52 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠127.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠127.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠155.7°.

Moon after perigee

5 days since point of perigee on 4 July 2023 at 22:28 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 20 July 2023 at 06:56 in ♌ Leo.

Distance to Moon 373 847 km

The Moon is 373 847 km (232 298 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 291 km (252 458 mi).

Moon before ascending node

11 days after descending node on 28 June 2023 at 12:22 in ♏ Scorpio 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 11 July 2023 at 01:23 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 3 July 2023 at 01:23 in ♑ Capricorn when the Moon has reached South declination of ∠-27.840° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.849° at the point of next northern standstill on 16 July 2023 at 02:40 in ♋ Cancer.

Draconic month

26 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 17 July 2023 at 18:32 in ♋ Cancer 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.
