Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 70% and getting smaller. Lunar cycle is 20 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 ∠13° of ♉ Taurus tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 22 August 2097 at 23:52.

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September 2097 after 24 days on 21 September 2097 at 13:00.

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 ∠1930"

Lunar disc appears visually 1.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1930" and ∠1900".

Lunation 1207 / 2160

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1207 of Meeus index or 2160 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 34 minutes and it is 2 hours and 38 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 10 minutes shorter than the mean synodic month length. It is 1 hour and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠26.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠26.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠47.4°.

Moon before perigee

10 days since point of apogee on 18 August 2097 at 03:05 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 2 September 2097 at 23:07 in ♋ Cancer.

Distance to Moon 371 382 km

The Moon is 371 382 km (230 766 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 365 774 km (227 281 mi).

Moon after ascending node

1 day after ascending node on 27 August 2097 at 22:42 in ♈ Aries the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 9 September 2097 at 17:26 in ♎ Libra.

Moon before northern standstill

10 days since the last southern standstill on 18 August 2097 at 11:45 in ♑ Capricorn when the Moon has reached South declination of ∠-27.633° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠27.741° at the point of next northern standstill on 1 September 2097 at 07:23 in ♋ Cancer.

Draconic month

1 day since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 6 September 2097 at 00:33 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.
