Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 96% 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 is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 29 August 2034 at 16:49.

Sturgeon Moon before 1 day

Next Full Moon is the Harvest Moon of September 2034 after 27 days on 28 September 2034 at 02:57.

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 ∠1933"

Lunar disc appears visually 1.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1933" and ∠1901".

Lunation 428 / 1381

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 428 of Meeus index or 1381 from Brown series.

Synodic month length 29.51 days

The length of this lunation is 29 days, 12 hours and 21 minutes and it is 2 hours and 58 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 23 minutes shorter than the mean synodic month length. It is 5 hours and 46 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠73.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠73.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠108.6°.

Moon before perigee

9 days since point of apogee on 21 August 2034 at 12:02 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 2 September 2034 at 15:31 in ♈ Aries.

Distance to Moon 370 737 km

The Moon is 370 737 km (230 365 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 367 629 km (228 434 mi).

Moon after descending node

1 day after descending node on 30 August 2034 at 22:58 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 12 September 2034 at 23:47 in ♍ Virgo.

Moon before northern standstill

6 days since the last southern standstill on 24 August 2034 at 17:42 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.219° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠18.184° at the point of next northern standstill on 6 September 2034 at 19:37 in ♊ Gemini.

Draconic month

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

Syzygy in 12 days

In 12 days on 12 September 2034 at 16:14 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.
