Moon phase and lunation details

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 12 September 2013 at 17:08.

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 ♒ Aquarius

Moon is passing about ∠14° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1955"

Lunar disc appears visually 2.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1955" and ∠1909".

Harvest Moon after 2 days

Next Full Moon is the Harvest Moon of September 2013 after 2 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 169 / 1122

The Moon is 11 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.

Synodic month length 29.54 days

The length of the lunation is 29 days, 12 hours and 58 minutes. It is 43 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 14 minutes longer than the mean synodic month length. It is 6 hours and 49 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠249.2°

At the beginning of the lunation cycle the true anomaly is ∠249.2°. At the beginning of next synodic month the true anomaly is going to be ∠285.3°.

Moon after perigee

1 day after point of perigee on 15 September 2013 at 16:34 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 11 days, until the Moon reaches the point of next apogee on 27 September 2013 at 18:17 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 366 551 km

The Moon is 366 551 km (227 764 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 309 km (251 226 mi).

Moon before descending node

6 days after ascending node on 9 September 2013 at 17:29 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 22 September 2013 at 13:48 in ♉ Taurus.

Draconic month

6 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

3 days since the previous standstill on 12 September 2013 at 18:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.685°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠19.599° at the point of next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.

Syzygy in 2 days

In 2 days on 19 September 2013 at 11:13 in ♓ Pisces 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.
