Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 66% and getting smaller. Lunar cycle is 20 days old.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠20° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 24 July 2078 at 22:07.

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2078 after 23 days on 23 August 2078 at 08:11.

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 ∠1966"

Lunar disc appears visually 3.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1890".

Lunation 971 / 1924

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 971 of Meeus index or 1924 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 43 minutes and it is 2 hours and 24 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 shorter than mean

The length of the current synodic month is 3 hours and 1 minute shorter than the mean synodic month length. It is 3 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠50.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠50.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠80.3°.

Moon before perigee

12 days since point of apogee on 18 July 2078 at 01:21 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 1 August 2078 at 02:41 in ♉ Taurus.

Distance to Moon 364 590 km

The Moon is 364 590 km (226 546 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 774 km (229 767 mi).

Moon before ascending node

11 days after descending node on 18 July 2078 at 20:35 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 1 August 2078 at 08:13 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 22 July 2078 at 23:47 in ♑ Capricorn when the Moon has reached South declination of ∠-27.072° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.132° at the point of next northern standstill on 5 August 2078 at 00:22 in ♋ Cancer.

Draconic month

25 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 8 days

In 8 days on 7 August 2078 at 19:52 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.
