Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 83% and getting smaller. Lunar cycle is 18 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 ∠3° of ♐ Sagittarius tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 31 March 2018 at 12:37.

Worm Moon before 3 days

Next Full Moon is the Pink Moon of April 2018 after 25 days on 30 April 2018 at 00:58.

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 ∠1797"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1797" and ∠1918".

Lunation 225 / 1178

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 225 of Meeus index or 1178 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 46 minutes and it is 2 hours and 55 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 minutes longer than the mean synodic month length. It is 7 hours and 1 minute shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠262.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠262.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠296.5°.

Moon before apogee

8 days since point of perigee on 26 March 2018 at 17:17 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 8 April 2018 at 05:32 in ♑ Capricorn.

Distance to Moon 398 898 km

The Moon is 398 898 km (247 864 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 145 km (251 124 mi).

Moon before descending node

8 days after ascending node on 27 March 2018 at 10:56 in ♌ Leo the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 10 April 2018 at 08:09 in ♒ Aquarius.

Moon before southern standstill

10 days since the last northern standstill on 25 March 2018 at 02:04 in ♋ Cancer when the Moon has reached North declination of ∠20.210° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-20.320° at the point of next southern standstill on 7 April 2018 at 14:37 in ♑ Capricorn.

Draconic month

8 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 11 days

In 11 days on 16 April 2018 at 01:57 in ♈ Aries 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.
