Waning Crescent in Gemini

Waning Crescent on . The illuminated surface of the moon is 36% and getting smaller. The lunar cycle is 23 days old.

Moonrise and moonset

The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠5° of ♊ Gemini tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 10 August 2031 at 00:24.

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2031 after 20 days on 1 September 2031 at 09:20.

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 ∠1796"

Lunar disc appears visually 5.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1893".

Lunation 390 / 1343

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 52 minutes and it is 37 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 2 hours and 8 minutes longer than the mean synodic month length. It is 4 hours and 55 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠188.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠188.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠213.5°.

Moon before apogee

9 days since point of perigee on 2 August 2031 at 06:47 in ♑ Capricorn 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 14 August 2031 at 21:37 in ♋ Cancer.

Distance to Moon 399 146 km

The Moon is 399 146 km (248 018 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 946 km (252 243 mi).

Moon after descending node

1 day after descending node on 10 August 2031 at 14:10 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 August 2031 at 01:21 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.951° the lunar orbit is extending northward over the next day to face maximum declination of ∠20.868° at the point of next northern standstill on 12 August 2031 at 15:58 in ♊ Gemini.

Draconic month

13 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 6 days

In 6 days on 18 August 2031 at 04:32 in ♌ Leo 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.
