Waxing Gibbous in Libra

Waxing Gibbous on . Illuminated surface of the Moon is 90% and growing larger. Lunar cycle is 12 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is leaving the last ∠1° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 22 May 2018 at 03:49.

Flower Moon after 3 days

Next Full Moon is the Flower Moon of May 2018 after 3 days on 29 May 2018 at 14:20.

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 ∠1857"

Lunar disc appears visually 2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1857" and ∠1894".

Lunation 227 / 1180

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 227 of Meeus index or 1180 from Brown series.

Synodic month length 29.33 days

The length of this lunation is 29 days, 7 hours and 55 minutes and it is 50 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 49 minutes shorter than the mean synodic month length. It is 1 hour and 20 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠321.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠321.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠340.3°.

Moon before apogee

8 days since point of perigee on 17 May 2018 at 21:06 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 7 days until the Moon reaches the point of next apogee on 2 June 2018 at 16:34 in ♑ Capricorn.

Distance to Moon 386 020 km

The Moon is 386 020 km (239 862 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 316 km (251 852 mi).

Moon after ascending node

5 days after ascending node on 20 May 2018 at 13:13 in ♌ Leo the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 3 June 2018 at 12:39 in ♒ Aquarius.

Moon before southern standstill

7 days since the last northern standstill on 18 May 2018 at 15:02 in ♋ Cancer when the Moon has reached North declination of ∠20.652° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-20.727° at the point of next southern standstill on 1 June 2018 at 07:09 in ♑ Capricorn.

Draconic month

5 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 3 days

In 3 days on 29 May 2018 at 14:20 in ♐ Sagittarius 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.
