Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 98% and getting smaller. Lunar cycle is 16 days old.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♐ Sagittarius

Moon is passing first ∠0° of ♐ Sagittarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 4 May 2015 at 03:42.

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2015 after 28 days on 2 June 2015 at 16:19.

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 ∠1839"

Lunar disc appears visually 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1902".

Lunation 189 / 1142

The Moon is 16 days old and navigating from the middle to the last 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

6 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 9 days until the Moon reaches the point of next perigee on 15 May 2015 at 00:23 in ♈ Aries.

Distance to Moon 389 775 km

The Moon is 389 775 km (242 195 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 366 024 km (227 437 mi).

Moon after ascending node

4 days after ascending node on 1 May 2015 at 09:50 in ♎ Libra the Moon is positioned north of the ecliptic over the following 9 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

12 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 2 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

4 days 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 12 days

In 12 days on 18 May 2015 at 04:13 in ♉ Taurus the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
