Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 72% and getting smaller. The lunar cycle is 20 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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♊ Gemini

Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 14 September 2084 at 09:15.

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2084 after 24 days on 13 October 2084 at 20:12.

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 ∠1804"

Lunar disc appears visually 5.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1804" and ∠1911".

Lunation 1047 / 2000

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1047 of Meeus index or 2000 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 32 minutes and it is 1 hour and 2 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 longer than mean

The length of the current synodic month is 48 minutes longer than the mean synodic month length. It is 6 hours and 15 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠232.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠232.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠268.2°.

Moon before apogee

7 days since point of perigee on 11 September 2084 at 14:43 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 23 September 2084 at 10:54 in ♋ Cancer.

Distance to Moon 397 411 km

The Moon is 397 411 km (246 940 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 391 km (251 277 mi).

Moon before descending node

9 days after ascending node on 9 September 2084 at 23:14 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 23 September 2084 at 08:24 in ♋ Cancer.

Moon before northern standstill

11 days since the last southern standstill on 7 September 2084 at 23:36 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.423° the lunar orbit is extending northward over the next day to face maximum declination of ∠25.317° at the point of next northern standstill on 21 September 2084 at 01:38 in ♊ Gemini.

Draconic month

9 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 29 September 2084 at 21:16 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.
