Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 16 August 2010 at 18:14.

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 ∠23° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1794"

Lunar disc appears visually 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1897".

Sturgeon Moon after 3 days

Next Full Moon is the Sturgeon Moon of August 2010 after 3 days on 24 August 2010 at 17:05.

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 131 / 1084

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 131 of Meeus index or 1084 from Brown series.

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 22 minutes. This is the year's shortest synodic month of 2010. It is 53 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 22 minutes shorter than the mean synodic month length. It is 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠349.5°

At the beginning of the lunation cycle the true anomaly is ∠349.5°. At the beginning of next synodic month the true anomaly is going to be ∠4.6°.

Moon before perigee

10 days after point of perigee on 10 August 2010 at 17:56 in ♌ Leo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next apogee on 25 August 2010 at 05:51 in ♓ Pisces.

Previous perigeeNext apogee

Distance to Moon 399 568 km

The Moon is 399 568 km (248 280 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 406 390 km (252 519 mi).

Moon after ascending node

1 day after ascending node on 20 August 2010 at 12:13 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 13 days, until the lunar orbit crosses from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.

Draconic month

1 day since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

2 days since the previous standstill on 18 August 2010 at 17:07 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.929°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠24.807° at the point of next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.

Syzygy in 3 days

In 3 days on 24 August 2010 at 17:05 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.
