Waning Crescent in Scorpio

Waning Crescent on . The illuminated surface of the moon is 19% and getting smaller. The lunar cycle is 25 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 ♏ Scorpio

Moon is passing about ∠25° of ♏ Scorpio tropical zodiac sector.

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 3 January 2100 at 13:03.

Wolf Moon after 19 days

Next Full Moon is the Wolf Moon of January 2100 after 19 days on 26 January 2100 at 02:49.

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 ∠1946"

Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1946" and ∠1951".

Lunation 1236 / 2189

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 1236 of Meeus index or 2189 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 47 minutes and it is 2 hours and 12 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 3 minutes longer than the mean synodic month length. It is 6 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠49.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠49.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠81.3°.

Moon after perigee

3 days since point of perigee on 3 January 2100 at 08:57 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 17 January 2100 at 10:48 in ♈ Aries.

Distance to Moon 368 294 km

The Moon is 368 294 km (228 847 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 404 420 km (251 295 mi).

Moon after descending node

4 days after descending node on 1 January 2100 at 21:13 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 January 2100 at 03:56 in ♓ Pisces.

Moon before southern standstill

10 days since the last northern standstill on 26 December 2099 at 23:34 in ♊ Gemini when the Moon has reached North declination of ∠28.345° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-28.379° at the point of next southern standstill on 8 January 2100 at 21:59 in ♐ Sagittarius.

Draconic month

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

Syzygy in 4 days

In 4 days on 10 January 2100 at 12:55 in ♑ Capricorn 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.
