Moon phase and lunation details
Moonrise and moonset
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon in ♎ Libra
Moon is leaving the last ∠3° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.
Apparent angular diameter ∠1930"
Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1930" and ∠1888".
Buck Moon after 7 days
Next Full Moon is the Buck Moon of July 2010 after 7 days on 26 July 2010 at 01:37.
Upcoming main Moon phases
- Full Moon in Aquarius ♒ on 26 July 2010 at 01:37
- Last Quarter in Taurus ♉ on 3 August 2010 at 04:59
- New Moon in Leo ♌ on 10 August 2010 at 03:08

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 130 / 1083
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 130 of Meeus index or 1083 from Brown series.
Synodic month length 29.31 days
The length of the lunation is 29 days, 7 hours and 28 minutes. It is 6 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 shorter than mean
The length of the current synodic month is 5 hours and 16 minutes shorter than the mean synodic month length. It is 53 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠332.7°
At the beginning of the lunation cycle the true anomaly is ∠332.7°. At the beginning of next synodic month the true anomaly is going to be ∠349.5°.
Moon after perigee
5 days after point of perigee on 13 July 2010 at 11:21 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 10 days, until the Moon reaches the point of next apogee on 28 July 2010 at 23:50 in ♓ Pisces.
Distance to Moon 371 330 km
The Moon is 371 330 km (230 734 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 955 km (252 249 mi).
Moon before ascending node
7 days after descending node on 11 July 2010 at 07:30 in ♋ Cancer. The Moon is located south of the ecliptic over the following 5 days, until the lunar orbit crosses from South to North in ascending node on 24 July 2010 at 07:59 in ♑ Capricorn.
Draconic month
21 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the second to the final part of the cycle.
Moon before southern standstill
8 days since the previous standstill on 9 July 2010 at 16:50 in ♊ Gemini when the Moon has reached North declination of ∠25.043°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-25.034° at the point of next southern standstill on 22 July 2010 at 11:12 in ♐ Sagittarius.
Syzygy in 7 days
In 7 days on 26 July 2010 at 01:37 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.
