Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 14 August 2013 at 10:56.

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 ∠20° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1970"

Lunar disc appears visually 3.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1896".

Sturgeon Moon after 2 days

Next Full Moon is the Sturgeon Moon of August 2013 after 2 days on 21 August 2013 at 01:45.

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 168 / 1121

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 168 of Meeus index or 1121 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.57 days

The length of the lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 1 hour and 1 minute longer than the mean synodic month length. It is 6 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠216.9°

At the beginning of the lunation cycle the true anomaly is ∠216.9°. At the beginning of next synodic month the true anomaly is going to be ∠249.2°.

Moon before apogee

15 days after point of apogee on 3 August 2013 at 08:53 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 19 August 2013 at 01:26 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 363 774 km

The Moon is 363 774 km (226 039 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 362 265 km (225 101 mi).

Moon after ascending node

4 days after ascending node on 13 August 2013 at 16:20 in ♏ Scorpio. 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 26 August 2013 at 08:19 in ♉ Taurus.

Draconic month

4 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

1 day since the previous standstill on 16 August 2013 at 12:06 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.906°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠19.801° at the point of next northern standstill on 29 August 2013 at 17:03 in ♊ Gemini.

Syzygy in 2 days

In 2 days on 21 August 2013 at 01:45 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.
