Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♏ Scorpio

Moon is passing about ∠6° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1856"

Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1856" and ∠1888".

Buck Moon after 7 days

Next Full Moon is the Buck Moon of July 2018 after 7 days on 27 July 2018 at 20:20.

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.

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 229 of Meeus index or 1182 from Brown series.

Synodic month length 29.3 days

The length of the lunation is 29 days, 7 hours and 10 minutes. It is 54 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 5 hours and 34 minutes shorter than the mean synodic month length. It is 35 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠356°

At the beginning of the lunation cycle the true anomaly is ∠356°. At the beginning of next synodic month the true anomaly is going to be ∠11.2°.

Moon before perigee

7 days after point of perigee on 13 July 2018 at 08:28 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 6 days, until the Moon reaches the point of next apogee on 27 July 2018 at 05:44 in ♑ Capricorn.

Distance to Moon 386 191 km

The Moon is 386 191 km (239 968 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 223 km (252 415 mi).

Moon after ascending node

6 days after ascending node on 14 July 2018 at 02:50 in ♌ Leo. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 27 July 2018 at 22:40 in ♑ Capricorn.

Moon before southern standstill

7 days since the previous standstill on 12 July 2018 at 12:01 in ♋ Cancer when the Moon has reached North declination of ∠20.761°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-20.755° at the point of next southern standstill on 25 July 2018 at 20:55 in ♑ Capricorn.

Syzygy in 7 days

In 7 days on 27 July 2018 at 20:20 in ♑ Capricorn 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.
