First Quarter in Leo

First Quarter on . The illuminated surface of the moon is 53% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 13 May 2027 at 04:44 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 ∠4° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Flower Moon after 6 days

Next Full Moon is the Flower Moon of May 2027 after 6 days on 20 May 2027 at 10:59.

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 ∠1960"

Lunar disc appears visually 3.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1960" and ∠1899".

Lunation 338 / 1291

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 338 of Meeus index or 1291 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 42 minutes and it is 1 hour 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 shorter than mean

The length of the current synodic month is 4 hours and 2 minutes shorter than the mean synodic month length. It is 2 hours and 7 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠308.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠308.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠330.4°.

Moon after perigee

3 days since point of perigee on 9 May 2027 at 20:07 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 25 May 2027 at 15:13 in ♑ Capricorn.

Distance to Moon 365 751 km

The Moon is 365 751 km (227 267 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 801 km (251 532 mi).

Moon after descending node

1 day after descending node on 12 May 2027 at 17:03 in ♌ Leo the Moon is positioned south of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 May 2027 at 15:22 in ♒ Aquarius.

Moon after northern standstill

4 days since the last northern standstill on 9 May 2027 at 01:45 in ♊ Gemini when the Moon has reached North declination of ∠27.225° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-27.162° at the point of next southern standstill on 22 May 2027 at 08:52 in ♐ Sagittarius.

Draconic month

13 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 20 May 2027 at 10:59 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.
