Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 21 August 2013 at 01:45.

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.

Moon in ♈ Aries

Moon is leaving the last ∠1° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Apparent angular diameter ∠1834"

Lunar disc appears visually 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1834" and ∠1899".

Sturgeon Moon before 4 days

Next Full Moon is the Harvest Moon of September 2013 after 24 days on 19 September 2013 at 11:13.

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 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.

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 perigee

6 days after point of perigee on 19 August 2013 at 01:26 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 30 August 2013 at 23:46 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 390 718 km

The Moon is 390 718 km (242 781 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 883 km (251 583 mi).

Moon before descending node

11 days after ascending node on 13 August 2013 at 16:20 in ♏ Scorpio. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 26 August 2013 at 08:19 in ♉ Taurus.

Draconic month

11 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 before northern standstill

8 days 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 4 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 10 days

In 10 days on 5 September 2013 at 11:36 in ♍ Virgo 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.
