Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 23 September 2010 at 09:17.

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 ♊ Gemini

Moon is passing about ∠16° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1880"

Lunar disc appears visually 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1916".

Harvest Moon before 6 days

Next Full Moon is the Hunter Moon of October 2010 after 23 days on 23 October 2010 at 01:36.

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 132 / 1085

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.34 days

The length of the lunation is 29 days, 8 hours and 15 minutes. It is 1 hour and 52 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 29 minutes shorter than the mean synodic month length. It is 1 hour and 40 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠4.6°

At the beginning of the lunation cycle the true anomaly is ∠4.6°. At the beginning of next synodic month the true anomaly is going to be ∠20.4°.

Moon before apogee

8 days after point of apogee on 21 September 2010 at 08:03 in ♓ Pisces. 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 6 October 2010 at 13:41 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 381 272 km

The Moon is 381 272 km (236 911 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 359 453 km (223 354 mi).

Moon before descending node

12 days after ascending node on 16 September 2010 at 13:56 in ♑ Capricorn. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 1 October 2010 at 02:42 in ♋ Cancer.

Draconic month

12 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 at northern standstill

At 17:37 the Moon is meeting its standstill point to reach North declination of ∠24.555°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-24.457° at the point of next standstill in ♐ Sagittarius on 12 October 2010 at 07:49.

Syzygy in 8 days

In 8 days on 7 October 2010 at 18:44 in ♎ Libra 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.
