Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 93% and getting smaller. The lunar cycle is 17 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 ♒ Aquarius

Moon is passing first ∠0° of ♒ Aquarius tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 19 July 2054 at 17:47.

Buck Moon before 2 days

Next Full Moon is the Sturgeon Moon of August 2054 after 26 days on 18 August 2054 at 09:22.

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 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1889".

Lunation 674 / 1627

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 674 of Meeus index or 1627 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 14 minutes and it is 16 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2054. 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 5 hours and 30 minutes shorter than the mean synodic month length. It is 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠336°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠336° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠352.3°.

Moon at apogee

Moon is at apogee at 05:49 about 15 days since last perigee on 6 July 2054 at 21:10 in ♋ Cancer 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 4 August 2054 at 04:47 in ♌ Leo.

Distance to Moon 405 947 km

This apogee Moon is 405 947 km (252 244 mi) away from Earth. It is 539 km further than the mean apogee distance, but it is still 762 km closer than the farthest apogee of 21st century.

Moon in descending node

Moon is in descending node in ♒ Aquarius at 09:02 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 4 August 2054 at 20:23 in ♌ Leo.

Moon after southern standstill

4 days since the last southern standstill on 18 July 2054 at 03:03 in ♑ Capricorn when the Moon has reached South declination of ∠-19.176° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠19.139° at the point of next northern standstill on 1 August 2054 at 11:52 in ♋ Cancer.

Draconic month

14 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 12 days

In 12 days on 3 August 2054 at 17:48 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.
