Waxing Gibbous in Aries

Waxing Gibbous on . Illuminated surface of the Moon is 83% and growing larger. Lunar cycle is 11 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 ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 10 November 2013 at 05:57.

Beaver Moon after 4 days

Next Full Moon is the Beaver Moon of November 2013 after 4 days on 17 November 2013 at 15:16.

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 ∠1896"

Lunar disc appears visually 2.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1896" and ∠1939".

Lunation 171 / 1124

The Moon is 11 days young and navigating from the first to the middle part of the current synodic month. This is lunation 171 of Meeus index or 1124 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 32 minutes and it is 40 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠315°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠315° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠336.4°.

Moon after perigee

7 days since point of perigee on 6 November 2013 at 09:28 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.

Distance to Moon 378 019 km

The Moon is 378 019 km (234 890 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 405 446 km (251 932 mi).

Moon before descending node

10 days after ascending node on 3 November 2013 at 06:52 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 16 November 2013 at 05:30 in ♉ Taurus.

Moon before northern standstill

7 days since the last southern standstill on 6 November 2013 at 06:43 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.511° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.534° at the point of next northern standstill on 19 November 2013 at 17:18 in ♊ Gemini.

Draconic month

10 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 4 days

In 4 days on 17 November 2013 at 15:16 in ♉ Taurus 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.
