Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 24 August 2010 at 17:05.

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 ♈ Aries

Moon is passing about ∠5° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1779"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1779" and ∠1899".

Sturgeon Moon before 2 days

Next Full Moon is the Harvest Moon of September 2010 after 26 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 131 / 1084

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 22 minutes. This is the year's shortest synodic month of 2010. It is 53 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 22 minutes shorter than the mean synodic month length. It is 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠349.5°

At the beginning of the lunation cycle the true anomaly is ∠349.5°. At the beginning of next synodic month the true anomaly is going to be ∠4.6°.

Moon after apogee

2 days after point of apogee on 25 August 2010 at 05:51 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 8 September 2010 at 04:00 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 402 890 km

The Moon is 402 890 km (250 344 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 357 193 km (221 949 mi).

Moon after ascending node

6 days after ascending node on 20 August 2010 at 12:13 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.

Previous nodeNext node

Draconic month

6 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

8 days since the previous standstill on 18 August 2010 at 17:07 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.929°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠24.807° at the point of next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.

Syzygy in 11 days

In 11 days on 8 September 2010 at 10:30 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.
