Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 99% and getting smaller. Lunar cycle is 15 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 ♒ Aquarius

Moon is leaving the last ∠4° of ♒ Aquarius tropical zodiac sector and will enter ♓ Pisces later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 5 August 2085 at 17:29.

Sturgeon Moon before 1 day

Next Full Moon is the Harvest Moon of September 2085 after 28 days on 4 September 2085 at 00:41.

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 ∠1973"

Lunar disc appears visually 4.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1892".

Lunation 1058 / 2011

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1058 of Meeus index or 2011 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 28 minutes and it is 28 minutes shorter 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 longer than mean

The length of the current synodic month is 2 hours and 44 minutes longer than the mean synodic month length. It is 4 hours and 19 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠156.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠156.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠180.2°.

Moon at perigee

Moon is at perigee at 03:30 about 12 days since last apogee on 24 July 2085 at 03:49 in ♌ Leo the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 13 days until point of next apogee on 20 August 2085 at 08:35 in ♌ Leo.

Distance to Moon 357 268 km

This perigee Moon is 357 268 km (221 996 mi) away from Earth. It is 5 240 km closer than the mean perigee distance, but it is still 13 088 km further than the closest perigee of 21st century.

Moon after ascending node

3 days after ascending node on 2 August 2085 at 20:43 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 15 August 2085 at 13:51 in ♊ Gemini.

Moon after southern standstill

4 days since the last southern standstill on 1 August 2085 at 23:37 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.052° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠23.995° at the point of next northern standstill on 14 August 2085 at 14:33 in ♊ Gemini.

Draconic month

3 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 13 days

In 13 days on 20 August 2085 at 09:10 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.
