Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 70% 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 in ♊ Gemini

Moon is passing about ∠17° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 29 September 2023 at 09:57.

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2023 after 24 days on 28 October 2023 at 20:24.

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 ∠1840"

Lunar disc appears visually 4.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1840" and ∠1918".

Lunation 293 / 1246

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 293 of Meeus index or 1246 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 15 minutes and it is 43 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2023. 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 3 hours and 31 minutes longer than the mean synodic month length. It is 3 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠202.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠202.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠232.5°.

Moon before apogee

6 days since point of perigee on 28 September 2023 at 01:05 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 10 October 2023 at 03:41 in ♌ Leo.

Distance to Moon 389 503 km

The Moon is 389 503 km (242 026 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 405 426 km (251 920 mi).

Moon after ascending node

3 days after ascending node on 30 September 2023 at 16:49 in ♈ Aries the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 15 October 2023 at 01:11 in ♎ Libra.

Moon before northern standstill

11 days since the last southern standstill on 23 September 2023 at 03:42 in ♑ Capricorn when the Moon has reached South declination of ∠-28.254° the lunar orbit is extending northward over the next day to face maximum declination of ∠28.294° at the point of next northern standstill on 5 October 2023 at 20:31 in ♊ Gemini.

Draconic month

3 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 14 October 2023 at 17:55 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.
