Last Quarter in Aries

Last Quarter on . Illuminated surface of the Moon is 55% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 25 July 2019 at 01:18 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 ∠25° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2019 after 22 days on 15 August 2019 at 12:29.

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 ∠1798"

Lunar disc appears visually 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1889".

Lunation 241 / 1194

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 241 of Meeus index or 1194 from Brown series.

Synodic month length 29.33 days

The length of this lunation is 29 days, 7 hours and 56 minutes and it is 31 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 4 hours and 48 minutes shorter than the mean synodic month length. It is 1 hour and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠321.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠321.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠340.5°.

Moon after apogee

3 days since point of apogee on 21 July 2019 at 00:01 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 2 August 2019 at 07:08 in ♌ Leo.

Distance to Moon 398 555 km

The Moon is 398 555 km (247 651 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 359 398 km (223 320 mi).

Moon before ascending node

8 days after descending node on 16 July 2019 at 09:05 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 July 2019 at 17:02 in ♋ Cancer.

Moon before northern standstill

8 days since the last southern standstill on 15 July 2019 at 22:49 in ♑ Capricorn when the Moon has reached South declination of ∠-22.375° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠22.384° at the point of next northern standstill on 30 July 2019 at 08:10 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 1 August 2019 at 03:12 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.
