Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 83% and getting smaller. Lunar cycle is 18 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 ♉ Taurus

Moon is passing about ∠18° of ♉ Taurus tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 18 September 2081 at 03:45.

Harvest Moon before 4 days

Next Full Moon is the Hunter Moon of October 2081 after 25 days on 17 October 2081 at 20:50.

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 ∠1817"

Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1817" and ∠1912".

Lunation 1010 / 1963

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1010 of Meeus index or 1963 from Brown series.

Synodic month length 29.35 days

The length of this lunation is 29 days, 8 hours and 22 minutes and it is 1 hour and 19 minutes shorter than the upcoming lunation's length. 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 4 hours and 22 minutes shorter than the mean synodic month length. It is 1 hour and 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠357.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠357.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠12.5°.

Moon after apogee

5 days since point of apogee on 17 September 2081 at 08:20 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 1 October 2081 at 23:44 in ♍ Virgo.

Distance to Moon 394 397 km

The Moon is 394 397 km (245 067 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 358 089 km (222 506 mi).

Moon after ascending node

5 days after ascending node on 17 September 2081 at 06:18 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 1 October 2081 at 01:46 in ♍ Virgo.

Moon before northern standstill

11 days since the last southern standstill on 10 September 2081 at 20:08 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.547° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠28.512° at the point of next northern standstill on 25 September 2081 at 14:31 in ♊ Gemini.

Draconic month

5 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 2 October 2081 at 17:23 in ♎ Libra 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.
