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 12 July 2020 at 23:29 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 leaving the last ∠3° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2020 after 21 days on 3 August 2020 at 15:59.

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 ∠1769"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1888".

Lunation 253 / 1206

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 253 of Meeus index or 1206 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 52 minutes and it is 1 hour and 43 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 shorter than mean

The length of the current synodic month is 1 hour and 53 minutes shorter than the mean synodic month length. It is 4 hours and 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠263.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠263.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠296.9°.

Moon after apogee

1 day since point of apogee on 12 July 2020 at 19:27 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 25 July 2020 at 04:54 in ♎ Libra.

Distance to Moon 405 248 km

The Moon is 405 248 km (251 809 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 368 367 km (228 893 mi).

Moon before ascending node

9 days after descending node on 4 July 2020 at 03:18 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 July 2020 at 12:33 in ♊ Gemini.

Moon before northern standstill

8 days since the last southern standstill on 5 July 2020 at 01:37 in ♑ Capricorn when the Moon has reached South declination of ∠-24.064° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠24.069° at the point of next northern standstill on 19 July 2020 at 11:51 in ♋ Cancer.

Draconic month

22 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 20 July 2020 at 17:33 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.
