Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 84% 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 ♈ Aries

Moon is leaving the last ∠1° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 31 August 2042 at 02:02.

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2042 after 25 days on 29 September 2042 at 10:34.

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 ∠1972"

Lunar disc appears visually 3.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1903".

Lunation 527 / 1480

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 527 of Meeus index or 1480 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 49 minutes and it is 2 hours and 24 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 5 minutes longer than the mean synodic month length. It is 4 hours and 58 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠123.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠123.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠152.7°.

Moon after perigee

1 day since point of perigee on 1 September 2042 at 15:49 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 17 September 2042 at 04:21 in ♎ Libra.

Distance to Moon 363 506 km

The Moon is 363 506 km (225 872 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 154 km (252 372 mi).

Moon after ascending node

1 day after ascending node on 2 September 2042 at 19:23 in ♈ Aries the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 16 September 2042 at 13:51 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 26 August 2042 at 11:39 in ♑ Capricorn when the Moon has reached South declination of ∠-28.327° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.396° at the point of next northern standstill on 8 September 2042 at 03:00 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 10 days

In 10 days on 14 September 2042 at 08:50 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.
