Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 93% and getting smaller. The lunar cycle is 17 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.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 20 October 2021 at 14:57.

Hunter Moon before 2 days

Next Full Moon is the Beaver Moon of November 2021 after 26 days on 19 November 2021 at 08:58.

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 ∠1769"

Lunar disc appears visually 8.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1929".

Lunation 269 / 1222

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 9 minutes and it is 19 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2021. 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 2 hours and 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠323.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠323.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠342.3°.

Moon before apogee

14 days since point of perigee on 8 October 2021 at 17:28 in ♏ Scorpio 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 24 October 2021 at 15:30 in ♊ Gemini.

Distance to Moon 405 221 km

The Moon is 405 221 km (251 793 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 616 km (252 038 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 11:47 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 6 November 2021 at 03:38 in ♐ Sagittarius.

Moon before northern standstill

11 days since the last southern standstill on 12 October 2021 at 09:09 in ♑ Capricorn when the Moon has reached South declination of ∠-26.204° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠26.291° at the point of next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.

New draconic month

At 11:47 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 12 days

In 12 days on 4 November 2021 at 21:15 in ♏ Scorpio 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.
