Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 78% and getting smaller. The lunar cycle is 19 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.

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♊ Gemini

Moon is passing first ∠2° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 24 September 2037 at 11:32.

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2037 after 24 days on 24 October 2037 at 04:36.

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 ∠1823"

Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1823" and ∠1916".

Lunation 466 / 1419

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 466 of Meeus index or 1419 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 9 minutes and it is 1 hour and 20 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 4 hours and 35 minutes shorter than the mean synodic month length. It is 1 hour and 34 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠354.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠354.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠9.6°.

Moon after apogee

5 days since point of apogee on 24 September 2037 at 03:44 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 8 October 2037 at 13:04 in ♍ Virgo.

Distance to Moon 393 168 km

The Moon is 393 168 km (244 303 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 357 513 km (222 148 mi).

Moon before ascending node

10 days after descending node on 19 September 2037 at 02:02 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 October 2037 at 15:23 in ♋ Cancer.

Moon before northern standstill

11 days since the last southern standstill on 17 September 2037 at 19:36 in ♑ Capricorn when the Moon has reached South declination of ∠-21.547° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠21.695° at the point of next northern standstill on 2 October 2037 at 13:57 in ♋ Cancer.

Draconic month

23 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 9 October 2037 at 02:34 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.
