Waxing Gibbous in Libra

Waxing Gibbous on . Illuminated surface of the Moon is 68% and growing larger. Lunar cycle is 9 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 is entering ♎ Libra

Moon is passing first ∠1° of ♎ Libra tropical zodiac sector.

1 day after First Quarter

Previous main lunar phase is the First Quarter before 1 day on 28 May 2012 at 20:16.

Strawberry Moon after 4 days

Next Full Moon is the Strawberry Moon of June 2012 after 4 days on 4 June 2012 at 11:12.

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 ∠1940"

Lunar disc appears visually 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1940" and ∠1892".

Lunation 153 / 1106

The Moon is 9 days young and navigating from the first to the middle part of the current synodic month. This is lunation 153 of Meeus index or 1106 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 15 minutes and it is 1 hour and 53 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 2 hours and 31 minutes longer than the mean synodic month length. It is 4 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠191.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠191.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠217.1°.

Moon before perigee

10 days since point of apogee on 19 May 2012 at 16:13 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 3 June 2012 at 13:19 in ♏ Scorpio.

Distance to Moon 369 485 km

The Moon is 369 485 km (229 587 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 358 483 km (222 751 mi).

Moon before ascending node

9 days after descending node on 21 May 2012 at 09:21 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 June 2012 at 20:38 in ♏ Scorpio.

Moon before southern standstill

8 days since the last northern standstill on 22 May 2012 at 11:13 in ♊ Gemini when the Moon has reached North declination of ∠21.709° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-21.714° at the point of next southern standstill on 4 June 2012 at 17:05 in ♐ Sagittarius.

Draconic month

23 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 4 days

In 4 days on 4 June 2012 at 11:12 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.
