Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 28 August 2013 at 09:35.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♋ Cancer

Moon is passing about ∠12° of ♋ Cancer tropical zodiac sector.

Next Full Moon is the Harvest Moon of September 2013 after 18 days on 19 September 2013 at 11:13.

Upcoming main Moon phases

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 24 days old. Earth's natural satellite is moving from the second to the final 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 after apogee

1 day after point of apogee on 30 August 2013 at 23:46 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 15 days, until the Moon reaches the point of next perigee on 15 September 2013 at 16:34 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 405 460 km

The Moon is 405 460 km (251 941 mi) away from Earth and getting closer over the next 15 days until the point perigee when Earth-Moon distance is going to be 367 388 km (228 284 mi).

Moon after descending node

5 days after descending node on 26 August 2013 at 08:19 in ♉ Taurus. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 9 September 2013 at 17:29 in ♏ Scorpio.

Draconic month

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

Moon after northern standstill

1 day since the previous standstill on 29 August 2013 at 17:03 in ♊ Gemini when the Moon has reached North declination of ∠19.801°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-19.685° at the point of next southern standstill on 12 September 2013 at 18:30 in ♐ Sagittarius.

Syzygy in 4 days

In 4 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.
