Waxing Gibbous in Aquarius

Waxing Gibbous on . Illuminated surface of the Moon is 80% and growing larger. Lunar cycle is 10 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 is entering ♒ Aquarius

Moon is passing first ∠2° of ♒ Aquarius tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 15 September 2010 at 05:50.

Harvest Moon after 4 days

Next Full Moon is the Harvest Moon of September 2010 after 4 days on 23 September 2010 at 09:17.

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.

Apparent angular diameter ∠1787"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1787" and ∠1910".

Lunation 132 / 1085

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 15 minutes and it is 1 hour and 52 minutes shorter than the upcoming lunation's length. 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 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 details for

True anomaly ∠4.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠4.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠20.4°.

Moon before apogee

10 days since 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 2 days until the Moon reaches the point of next apogee on 21 September 2010 at 08:03 in ♓ Pisces.

Distance to Moon 401 073 km

The Moon is 401 073 km (249 215 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 406 169 km (252 382 mi).

Moon after ascending node

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

Moon after southern standstill

3 days since the last southern 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 11 days to face maximum declination of ∠24.555° at the point of next northern standstill on 29 September 2010 at 17:37 in ♊ Gemini.

Draconic month

1 day 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 4 days

In 4 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.
