Waxing Gibbous in Libra

Waxing Gibbous on . Illuminated surface of the Moon is 97% and growing larger. Lunar cycle is 13 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 ∠23° of ♎ Libra tropical zodiac sector.

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 25 April 2015 at 23:55.

Flower Moon after 1 day

Next Full Moon is the Flower Moon of May 2015 after 1 day on 4 May 2015 at 03:42.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1787"

Lunar disc appears visually 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1787" and ∠1904".

Lunation 189 / 1142

The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 189 of Meeus index or 1142 from Brown series.

Synodic month length 29.39 days

The length of this lunation is 29 days, 9 hours and 16 minutes and it is 36 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2015. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 3 hours and 28 minutes shorter than the mean synodic month length. It is 2 hours and 41 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠27.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠27.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠48.8°.

Moon after apogee

3 days since point of apogee on 29 April 2015 at 03:55 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next perigee on 15 May 2015 at 00:23 in ♈ Aries.

Distance to Moon 401 146 km

The Moon is 401 146 km (249 261 mi) away from Earth and getting closer over the next 12 days until the point perigee when Earth-Moon distance is going to be 366 024 km (227 437 mi).

Moon after ascending node

1 day after ascending node on 1 May 2015 at 09:50 in ♎ Libra the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 14 May 2015 at 20:37 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 22 April 2015 at 23:26 in ♊ Gemini when the Moon has reached North declination of ∠18.280° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-18.343° at the point of next southern standstill on 7 May 2015 at 13:39 in ♐ Sagittarius.

Draconic month

1 day since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 1 day

In 1 day on 4 May 2015 at 03:42 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.
