Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 6 August 2009 at 00:55.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♓ Pisces

Moon is leaving the last ∠4° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.

Apparent angular diameter ∠1821"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1893".

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2009 after 26 days on 4 September 2009 at 16:03.

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 18 days old. Earth's natural satellite is moving from the middle to the last 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 after apogee

5 days after point of apogee on 4 August 2009 at 00:42 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 393 710 km

The Moon is 393 710 km (244 640 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 359 642 km (223 471 mi).

Moon after ascending node

4 days after ascending node on 4 August 2009 at 21:42 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 18 August 2009 at 14:06 in ♋ Cancer.

Draconic month

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

Moon before northern standstill

7 days since the previous standstill on 1 August 2009 at 13:28 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.478°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠26.442° at the point of next northern standstill on 15 August 2009 at 21:54 in ♊ Gemini.

Syzygy in 10 days

In 10 days on 20 August 2009 at 10:01 in ♌ Leo 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.
