Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 96% and getting smaller. The lunar cycle is 16 days old.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠25° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 21 September 2078 at 17:31.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2078 after 27 days on 21 October 2078 at 02:55.

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 ∠1966"

Lunar disc appears visually 2.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1913".

Lunation 973 / 1926

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 973 of Meeus index or 1926 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 7 minutes and it is 2 hours and 43 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 longer than mean

The length of the current synodic month is 2 hours and 23 minutes longer than the mean synodic month length. It is 4 hours and 40 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠115.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠115.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠146.4°.

Moon at perigee

Moon is at perigee at 13:38 about 11 days since last apogee on 11 September 2078 at 14:50 in ♏ Scorpio the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 9 October 2078 at 06:58 in ♏ Scorpio.

Distance to Moon 361 662 km

This perigee Moon is 361 662 km (224 726 mi) away from Earth. It is 846 km closer than the mean perigee distance, but it is still 8 694 km further than the closest perigee of 21st century.

Moon before ascending node

12 days after descending node on 11 September 2078 at 01:26 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 24 September 2078 at 13:18 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 15 September 2078 at 16:23 in ♑ Capricorn when the Moon has reached South declination of ∠-27.437° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠27.518° at the point of next northern standstill on 28 September 2078 at 11:14 in ♋ Cancer.

Draconic month

26 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 5 October 2078 at 23:06 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.
