Waxing Gibbous in Libra

Waxing Gibbous on . Illuminated surface of the Moon is 77% and growing larger. Lunar cycle is 10 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 passing about ∠22° of ♎ Libra tropical zodiac sector.

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 9 June 2011 at 02:11.

Strawberry Moon after 4 days

Next Full Moon is the Strawberry Moon of June 2011 after 4 days on 15 June 2011 at 20:13.

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 ∠1970"

Lunar disc appears visually 4.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1890".

Lunation 141 / 1094

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 141 of Meeus index or 1094 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 51 minutes and it is 2 hours and 5 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 53 minutes shorter than the mean synodic month length. It is 5 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠248.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠248.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠283.1°.

Moon before perigee

15 days since point of apogee on 27 May 2011 at 09:58 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 12 June 2011 at 01:42 in ♏ Scorpio.

Distance to Moon 363 836 km

The Moon is 363 836 km (226 077 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 367 188 km (228 160 mi).

Moon before ascending node

8 days after descending node on 2 June 2011 at 20:21 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 15 June 2011 at 18:35 in ♐ Sagittarius.

Moon before southern standstill

9 days since the last northern standstill on 2 June 2011 at 09:54 in ♊ Gemini when the Moon has reached North declination of ∠23.393° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-23.399° at the point of next southern standstill on 15 June 2011 at 08:52 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 15 June 2011 at 20:13 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.
