First Quarter in Leo

First Quarter on . The illuminated surface of the moon is 57% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 22 April 2018 at 21:46 UTC.

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♌ Leo

Moon is passing about ∠11° of ♌ Leo tropical zodiac sector.

Pink Moon after 6 days

Next Full Moon is the Pink Moon of April 2018 after 6 days on 30 April 2018 at 00:58.

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 ∠1965"

Lunar disc appears visually 3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1965" and ∠1908".

Lunation 226 / 1179

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 226 of Meeus index or 1179 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 51 minutes and it is 1 hour and 56 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 53 minutes shorter than the mean synodic month length. It is 3 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠296.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠296.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠321.7°.

Moon after perigee

2 days since point of perigee on 20 April 2018 at 14:44 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 6 May 2018 at 00:35 in ♑ Capricorn.

Distance to Moon 364 733 km

The Moon is 364 733 km (226 635 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 458 km (251 319 mi).

Moon in ascending node

Moon is in ascending node in ♌ Leo at 12:19 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 7 May 2018 at 10:24 in ♒ Aquarius.

Moon after northern standstill

2 days since the last northern standstill on 21 April 2018 at 07:38 in ♋ Cancer when the Moon has reached North declination of ∠20.445° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-20.562° at the point of next southern standstill on 4 May 2018 at 23:00 in ♑ Capricorn.

New draconic month

At 12:19 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 30 April 2018 at 00:58 in ♏ Scorpio the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
