Waning Crescent in Aquarius

Waning Crescent on . The illuminated surface of the moon is 16% 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 ♒ Aquarius

Moon is passing about ∠7° of ♒ Aquarius tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 9 March 2018 at 11:20.

Worm Moon after 18 days

Next Full Moon is the Worm Moon of March 2018 after 18 days on 31 March 2018 at 12:37.

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 ∠1776"

Lunar disc appears visually 8.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1930".

Lunation 224 / 1177

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 224 of Meeus index or 1177 from Brown series.

Synodic month length 29.67 days

The length of this lunation is 29 days, 16 hours and 6 minutes and it is 3 hours and 20 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 3 hours and 22 minutes longer than the mean synodic month length. It is 3 hours and 41 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠227.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠227.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠262.6°.

Moon after apogee

2 days since point of apogee on 11 March 2018 at 09:13 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next perigee on 26 March 2018 at 17:17 in ♋ Cancer.

Distance to Moon 403 666 km

The Moon is 403 666 km (250 826 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 369 104 km (229 351 mi).

Moon before descending node

13 days after ascending node on 28 February 2018 at 05:03 in ♌ Leo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 14 March 2018 at 03:48 in ♒ Aquarius.

Moon after southern standstill

2 days since the last southern standstill on 11 March 2018 at 06:39 in ♑ Capricorn when the Moon has reached South declination of ∠-20.112° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠20.210° at the point of next northern standstill on 25 March 2018 at 02:04 in ♋ Cancer.

Draconic month

13 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 4 days

In 4 days on 17 March 2018 at 13:12 in ♓ Pisces 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.
