Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 74% and getting smaller. The lunar cycle is 19 days old.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon is entering ♈ Aries

Moon is passing first ∠3° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 19 July 2073 at 05:04.

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2073 after 24 days on 17 August 2073 at 17:45.

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 ∠1771"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1889".

Lunation 909 / 1862

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 909 of Meeus index or 1862 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 48 minutes and it is 59 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 2 hours and 56 minutes shorter than the mean synodic month length. It is 3 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠284.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠284.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠313.1°.

Moon before apogee

13 days since point of perigee on 11 July 2073 at 07:01 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 25 July 2073 at 19:45 in ♈ Aries.

Distance to Moon 404 820 km

The Moon is 404 820 km (251 543 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 365 km (251 261 mi).

Moon after descending node

3 days after descending node on 21 July 2073 at 02:27 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 August 2073 at 08:57 in ♌ Leo.

Moon after southern standstill

6 days since the last southern standstill on 17 July 2073 at 20:15 in ♑ Capricorn when the Moon has reached South declination of ∠-19.591° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠19.570° at the point of next northern standstill on 1 August 2073 at 07:46 in ♋ Cancer.

Draconic month

16 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 10 days

In 10 days on 3 August 2073 at 17:04 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.
