Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 98% and getting smaller. Lunar cycle is 16 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 passing about ∠14° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 20 September 2070 at 07:47.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2070 after 28 days on 19 October 2070 at 18:59.

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 ∠1911"

Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1911" and ∠1912".

Lunation 874 / 1827

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 874 of Meeus index or 1827 from Brown series.

Synodic month length 29.52 days

The length of this lunation is 29 days, 12 hours and 33 minutes and it is 3 hours and 8 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 11 minutes shorter than the mean synodic month length. It is 5 hours and 58 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠66.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠66.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠100.2°.

Moon before perigee

8 days since point of apogee on 12 September 2070 at 12:02 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 24 September 2070 at 22:02 in ♉ Taurus.

Distance to Moon 375 177 km

The Moon is 375 177 km (233 124 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 368 697 km (229 098 mi).

Moon in descending node

Moon is in descending node in ♈ Aries at 16:24 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 4 October 2070 at 16:29 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 13 September 2070 at 00:50 in ♑ Capricorn when the Moon has reached South declination of ∠-18.435° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.394° at the point of next northern standstill on 26 September 2070 at 13:29 in ♊ Gemini.

Draconic month

14 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 4 October 2070 at 07:01 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.
