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.

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

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

Length of current 131 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 next lunation 132 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 22 minutes shorter than the mean length of synodic month, but it is still 47 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠349.5°

This New Moon true anomaly is ∠349.5°. At beginning of next synodic month true anomaly will be ∠4.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before apogee

10 days after point of perigee on 10 August 2010 at 17:56 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 25 August 2010 at 05:51 in ♓ Pisces.

Previous perigeeNext apogee

Distance to Moon 399 568 km

Moon is 399 568 km (248 280 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 406 390 km (252 519 mi).

Moon after ascending node

1 day after its ascending node on 20 August 2010 at 12:13 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 13 days, until it will cross the ecliptic from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.

Moon after southern standstill

2 days after previous South standstill on 18 August 2010 at 17:07 in ♐ Sagittarius, when Moon has reached southern declination of ∠-24.929°. Next 11 days the lunar orbit moves northward to face North declination of ∠24.807° in the next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.

Syzygy in 3 days

After 3 days on 24 August 2010 at 17:05 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
