Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 4 September 2009 at 16:03.

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 is entering ♉ Taurus

Moon is passing first ∠1° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1876"

Lunar disc appears visually 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1876" and ∠1905".

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2009 after 25 days on 4 October 2009 at 06:10.

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 119 / 1072

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 119 of Meeus index or 1072 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.36 days

The length of the lunation is 29 days, 8 hours and 43 minutes. It is 2 hours and 6 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 4 hours and 1 minute shorter than the mean synodic month length. It is 2 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠20.3°

At the beginning of the lunation cycle the true anomaly is ∠20.3°. At the beginning of next synodic month the true anomaly is going to be ∠39.3°.

Moon before apogee

8 days after point of apogee on 31 August 2009 at 11:04 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 16 September 2009 at 07:55 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 382 087 km

The Moon is 382 087 km (237 418 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 364 054 km (226 213 mi).

Moon before descending node

7 days after ascending node on 1 September 2009 at 03:18 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 14 September 2009 at 20:56 in ♋ Cancer.

Draconic month

7 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

10 days since the previous standstill on 28 August 2009 at 20:17 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.391°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠26.289° at the point of next northern standstill on 12 September 2009 at 04:36 in ♊ Gemini.

Syzygy in 10 days

In 10 days on 18 September 2009 at 18:44 in ♍ Virgo 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.
