Waxing Gibbous in Aquarius

Waxing Gibbous on . Illuminated surface of the Moon is 99% and growing larger. Lunar cycle is 13 days young.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠17° of ♒ Aquarius tropical zodiac sector.

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 16 August 2010 at 18:14.

Sturgeon Moon after 1 day

Next Full Moon is the Sturgeon Moon of August 2010 after 1 day on 24 August 2010 at 17:05.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1773"

Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1898".

Lunation 131 / 1084

The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 22 minutes and it is 53 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2010. The lengths of the following synodic months are going to increase with the lunar orbit 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 details for

True anomaly ∠349.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠349.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠4.6°.

Moon before apogee

12 days since point of perigee on 10 August 2010 at 17:56 in ♌ Leo 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 25 August 2010 at 05:51 in ♓ Pisces.

Distance to Moon 404 283 km

The Moon is 404 283 km (251 210 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 390 km (252 519 mi).

Moon after ascending node

2 days after ascending node on 20 August 2010 at 12:13 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.

Moon after southern standstill

4 days since the last southern 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 9 days to face maximum declination of ∠24.807° at the point of next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.

Draconic month

2 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 1 day

In 1 day on 24 August 2010 at 17:05 in ♒ Aquarius 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.
