First Quarter in Leo

First Quarter on . The illuminated surface of the moon is 62% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 4 May 2055 at 11:10 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 leaving the last ∠2° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Flower Moon after 5 days

Next Full Moon is the Flower Moon of May 2055 after 5 days on 11 May 2055 at 02:31.

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 ∠1962"

Lunar disc appears visually 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1962" and ∠1902".

Lunation 684 / 1637

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 684 of Meeus index or 1637 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 40 minutes and it is 2 hours and 22 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 56 minutes longer than the mean synodic month length. It is 6 hours and 7 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠221.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠221.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠254.3°.

Moon before perigee

12 days since point of apogee on 23 April 2055 at 01:56 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 8 May 2055 at 21:10 in ♎ Libra.

Distance to Moon 365 288 km

The Moon is 365 288 km (226 979 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 363 012 km (225 565 mi).

Moon after ascending node

1 day after ascending node on 4 May 2055 at 12:19 in ♌ Leo the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 17 May 2055 at 07:26 in ♒ Aquarius.

Moon after northern standstill

3 days since the last northern standstill on 1 May 2055 at 22:10 in ♋ Cancer when the Moon has reached North declination of ∠20.193° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-20.280° at the point of next southern standstill on 14 May 2055 at 15:50 in ♑ Capricorn.

Draconic month

1 day 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 5 days

In 5 days on 11 May 2055 at 02:31 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.
