Waning Crescent in Gemini

Waning Crescent on . The illuminated surface of the moon is 35% 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 ∠24° of ♊ Gemini tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 27 August 2100 at 22:36.

Harvest Moon after 19 days

Next Full Moon is the Harvest Moon of September 2100 after 19 days on 18 September 2100 at 11:32.

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 ∠1798"

Lunar disc appears visually 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1900".

Lunation 1244 / 2197

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 1244 of Meeus index or 2197 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 48 minutes and it is 35 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 2 hours and 56 minutes shorter than the mean synodic month length. It is 3 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠294.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠294.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠320.8°.

Moon after apogee

3 days since point of apogee on 25 August 2100 at 23:00 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 6 September 2100 at 19:23 in ♎ Libra.

Distance to Moon 398 732 km

The Moon is 398 732 km (247 761 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 363 868 km (226 097 mi).

Moon before descending node

8 days after ascending node on 20 August 2100 at 18:39 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 4 September 2100 at 02:42 in ♍ Virgo.

Moon at northern standstill

At 17:37 the Moon is meeting its standstill point to reach North declination of ∠28.356°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.345° at the point of next southern standstill in ♐ Sagittarius on 11 September 2100 at 14:42.

Draconic month

8 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 5 days

In 5 days on 4 September 2100 at 08:49 in ♍ Virgo 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.
