Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 15 September 2010 at 05:50.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♒ Aquarius

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

Apparent angular diameter ∠1770"

Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1911".

Harvest Moon after 2 days

Next Full Moon is the Harvest Moon of September 2010 after 2 days on 23 September 2010 at 09:17.

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 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.

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 perigee

12 days after point of perigee on 8 September 2010 at 04:00 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 21 September 2010 at 08:03 in ♓ Pisces.

Previous perigeeNext apogee

Distance to Moon 404 944 km

The Moon is 404 944 km (251 621 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 169 km (252 382 mi).

Moon after ascending node

3 days after ascending node on 16 September 2010 at 13:56 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 1 October 2010 at 02:42 in ♋ Cancer.

Draconic month

3 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 after southern standstill

5 days since the previous standstill on 14 September 2010 at 23:47 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.710°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠24.555° at the point of next northern standstill on 29 September 2010 at 17:37 in ♊ Gemini.

Syzygy in 2 days

In 2 days on 23 September 2010 at 09:17 in ♈ Aries 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.
