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 ♏ Scorpio

Moon is passing about ∠13° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1834"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1834" and ∠1890".

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2009 after 7 days on 6 August 2009 at 00:55.

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 118 / 1071

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 118 of Meeus index or 1071 from Brown series.

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 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 17 minutes shorter than the mean synodic month length. It is 52 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠4.5°

At the beginning of the lunation cycle the true anomaly is ∠4.5°. At the beginning of next synodic month the true anomaly is going to be ∠20.3°.

Moon before perigee

7 days after point of perigee on 21 July 2009 at 20:16 in ♋ Cancer. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 4 August 2009 at 00:42 in ♑ Capricorn.

Distance to Moon 390 859 km

The Moon is 390 859 km (242 869 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 027 km (252 293 mi).

Moon before ascending node

7 days after descending node on 22 July 2009 at 03:47 in ♌ Leo. The Moon is located south of the ecliptic over the following 6 days, until the lunar orbit crosses from South to North in ascending node on 4 August 2009 at 21:42 in ♑ Capricorn.

Draconic month

20 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

9 days since the previous standstill on 19 July 2009 at 13:01 in ♊ Gemini when the Moon has reached North declination of ∠26.477°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-26.478° at the point of next southern standstill on 1 August 2009 at 13:28 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 6 August 2009 at 00:55 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.
