Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 76% 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.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠13° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 2 October 2039 at 07:23.

Hunter Moon before 5 days

Next Full Moon is the Hunter Moon of October 2039 after 24 days on 31 October 2039 at 22:36.

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 ∠1769"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1920".

Lunation 491 / 1444

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 491 of Meeus index or 1444 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 46 minutes and it is 9 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 1 hour and 58 minutes shorter than the mean synodic month length. It is 4 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠294.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠294.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠321.1°.

Moon before apogee

14 days since point of perigee on 23 September 2039 at 02:18 in ♐ Sagittarius 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 8 October 2039 at 10:06 in ♊ Gemini.

Distance to Moon 405 244 km

The Moon is 405 244 km (251 807 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 575 km (251 391 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 15:37 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 21 October 2039 at 04:37 in ♐ Sagittarius.

Moon before northern standstill

11 days since the last southern standstill on 25 September 2039 at 19:27 in ♑ Capricorn when the Moon has reached South declination of ∠-25.118° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.247° at the point of next northern standstill on 9 October 2039 at 20:04 in ♋ Cancer.

New draconic month

At 15:37 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 10 days

In 10 days on 17 October 2039 at 19:09 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.
