Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 73% 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 is entering ♉ Taurus

Moon is passing first ∠1° of ♉ Taurus tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 14 August 2038 at 22:57.

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September 2038 after 24 days on 13 September 2038 at 12:24.

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 ∠1768"

Lunar disc appears visually 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1897".

Lunation 477 / 1430

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 477 of Meeus index or 1430 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 32 minutes and it is 47 minutes longer 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 shorter than mean

The length of the current synodic month is 3 hours and 12 minutes shorter than the mean synodic month length. It is 2 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠293.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠293.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠319.9°.

Moon before apogee

14 days since point of perigee on 5 August 2038 at 21:36 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 21 August 2038 at 01:57 in ♉ Taurus.

Distance to Moon 405 419 km

The Moon is 405 419 km (251 916 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 583 km (251 396 mi).

Moon before ascending node

8 days after descending node on 11 August 2038 at 18:25 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 August 2038 at 03:40 in ♋ Cancer.

Moon before northern standstill

8 days since the last southern standstill on 11 August 2038 at 22:09 in ♑ Capricorn when the Moon has reached South declination of ∠-23.076° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠23.151° at the point of next northern standstill on 26 August 2038 at 08:58 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 30 August 2038 at 10:13 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.
