Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 71% 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 ♈ Aries

Moon is leaving the last ∠2° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 10 August 2014 at 18:09.

Sturgeon Moon before 4 days

Next Full Moon is the Harvest Moon of September 2014 after 24 days on 9 September 2014 at 01:38.

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 ∠1907"

Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1895".

Lunation 180 / 1133

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 180 of Meeus index or 1133 from Brown series.

Synodic month length 29.65 days

The length of this lunation is 29 days, 15 hours and 31 minutes and it is 30 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 47 minutes longer than the mean synodic month length. It is 4 hours and 16 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠169.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠169.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠192.1°.

Moon after perigee

4 days since point of perigee on 10 August 2014 at 17:43 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 24 August 2014 at 06:09 in ♌ Leo.

Distance to Moon 375 858 km

The Moon is 375 858 km (233 547 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 523 km (252 602 mi).

Moon in descending node

Moon is in descending node in ♈ Aries at 00:18 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 29 August 2014 at 13:14 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 7 August 2014 at 04:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.827° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.750° at the point of next northern standstill on 19 August 2014 at 22:12 in ♊ Gemini.

Draconic month

13 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 10 days

In 10 days on 25 August 2014 at 14:13 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.
