Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 88% 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 ∠16° of ♉ Taurus tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 25 September 2018 at 02:53.

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2018 after 26 days on 24 October 2018 at 16:45.

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 ∠1887"

Lunar disc appears visually 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1887" and ∠1915".

Lunation 231 / 1184

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 231 of Meeus index or 1184 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 45 minutes and it is 2 hours and 30 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 2 hours and 59 minutes shorter than the mean synodic month length. It is 3 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠28°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠28° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.6°.

Moon before perigee

8 days since point of apogee on 20 September 2018 at 00:54 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 5 October 2018 at 22:29 in ♌ Leo.

Distance to Moon 379 751 km

The Moon is 379 751 km (235 966 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 366 396 km (227 668 mi).

Moon before ascending node

8 days after descending node on 20 September 2018 at 09:30 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 October 2018 at 03:10 in ♌ Leo.

Moon before northern standstill

10 days since the last southern standstill on 18 September 2018 at 09:35 in ♑ Capricorn when the Moon has reached South declination of ∠-20.909° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠21.037° at the point of next northern standstill on 2 October 2018 at 13:03 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 10 days

In 10 days on 9 October 2018 at 03:47 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.
