Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 80% 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 in ♈ Aries

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

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 17 August 2073 at 17:45.

Sturgeon Moon before 4 days

Next Full Moon is the Harvest Moon of September 2073 after 24 days on 16 September 2073 at 08:52.

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 ∠1768"

Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1898".

Lunation 910 / 1863

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 910 of Meeus index or 1863 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 49 minutes and it is 20 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 3 hours and 55 minutes shorter than the mean synodic month length. It is 2 hours and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠313.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠313.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠334.3°.

Moon at apogee

Moon is at apogee at 13:26 about 15 days since last perigee on 6 August 2073 at 17:22 in ♍ Virgo the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 3 September 2073 at 14:51 in ♍ Virgo.

Distance to Moon 405 225 km

This apogee Moon is 405 225 km (251 795 mi) away from Earth. It is 183 km further than the mean apogee distance, but it is still 1 484 km closer than the farthest apogee of 21st century.

Moon after descending node

5 days after descending node on 17 August 2073 at 10:02 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 31 August 2073 at 18:55 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 14 August 2073 at 02:57 in ♑ Capricorn when the Moon has reached South declination of ∠-19.556° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.572° at the point of next northern standstill on 28 August 2073 at 17:17 in ♋ Cancer.

Draconic month

18 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 2 September 2073 at 01:52 in ♍ Virgo 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.
