Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 30 July 2017 at 15:23.

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.

Moon in ♑ Capricorn

Moon is passing about ∠6° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1772"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1891".

Sturgeon Moon after 3 days

Next Full Moon is the Sturgeon Moon of August 2017 after 3 days on 7 August 2017 at 18:11.

Upcoming main Moon phases

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.

Lunation 217 / 1170

The Moon is 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.36 days

The length of the lunation is 29 days, 8 hours and 45 minutes. It is 2 hours and 15 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠27.9°

At the beginning of the lunation cycle the true anomaly is ∠27.9°. At the beginning of next synodic month the true anomaly is going to be ∠49.5°.

Moon after apogee

1 day after point of apogee on 2 August 2017 at 17:55 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 14 days, until the Moon reaches the point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 404 474 km

The Moon is 404 474 km (251 328 mi) away from Earth and getting closer over the next 14 days until the point perigee when Earth-Moon distance is going to be 366 129 km (227 502 mi).

Moon before descending node

10 days after ascending node on 25 July 2017 at 00:46 in ♍ Virgo. The Moon is located north of the ecliptic over the following 3 days, until the lunar orbit crosses from North to South in descending node on 8 August 2017 at 10:56 in ♒ Aquarius.

Draconic month

10 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the beginning to the first part of the cycle.

Moon at southern standstill

At 18:17 the Moon is meeting its standstill point to reach South declination of ∠-19.393°. Over the next 13 days the lunar orbit is going to extend northward to face maximum declination of ∠19.381° at the point of next standstill in ♋ Cancer on 18 August 2017 at 06:50.

Previous standstillNext standstill

Syzygy in 3 days

In 3 days on 7 August 2017 at 18:11 in ♒ Aquarius 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.
