Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 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 ♒ Aquarius

Moon is passing about ∠25° of ♒ Aquarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 28 July 2045 at 22:11.

Buck Moon before 1 day

Next Full Moon is the Sturgeon Moon of August 2045 after 28 days on 27 August 2045 at 14:08.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1890".

Lunation 563 / 1516

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 563 of Meeus index or 1516 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 11 minutes and it is 37 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2045. 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 5 hours and 33 minutes shorter than the mean synodic month length. It is 36 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠345.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠345.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠0.7°.

Moon at apogee

Moon is at apogee at 02:00 about 14 days since last perigee on 15 July 2045 at 07:12 in ♌ Leo the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 13 days until point of next perigee on 12 August 2045 at 16:40 in ♌ Leo.

Distance to Moon 406 198 km

This apogee Moon is 406 198 km (252 400 mi) away from Earth. It is 790 km further than the mean apogee distance, but it is still 511 km closer than the farthest apogee of 21st century.

Moon in ascending node

Moon is in ascending node in ♒ Aquarius at 07:42 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 12 August 2045 at 21:20 in ♌ Leo.

Moon after southern standstill

5 days since the last southern standstill on 25 July 2045 at 09:40 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.770° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠27.798° at the point of next northern standstill on 8 August 2045 at 22:31 in ♊ Gemini.

New draconic month

At 07:42 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 13 days

In 13 days on 12 August 2045 at 17:39 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.
