Waxing Gibbous in Aquarius

Waxing Gibbous on . The illuminated surface of the moon is 90% and growing larger. The lunar cycle is 12 days young.

Moonrise and moonset

The 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 phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠25° of ♒ Aquarius tropical zodiac sector.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 21 September 2015 at 08:59.

Harvest Moon after 2 days

Next Full Moon is the Harvest Moon of September 2015 after 2 days on 28 September 2015 at 02:50.

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 ∠1952"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1952" and ∠1913".

Lunation 194 / 1147

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 194 of Meeus index or 1147 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 24 minutes and it is 17 minutes shorter 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 longer than mean

The length of the current synodic month is 4 hours and 40 minutes longer than the mean synodic month length. It is 2 hours and 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠169.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠169.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠192.9°.

Moon before perigee

11 days since point of apogee on 14 September 2015 at 11:28 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 28 September 2015 at 01:46 in ♈ Aries.

Distance to Moon 367 183 km

The Moon is 367 183 km (228 157 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 356 877 km (221 753 mi).

Moon before descending node

11 days after ascending node on 14 September 2015 at 04:38 in ♎ Libra 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 27 September 2015 at 21:04 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 21 September 2015 at 12:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.134° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠18.140° at the point of next northern standstill on 3 October 2015 at 23:55 in ♊ Gemini.

Draconic month

11 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 2 days

In 2 days on 28 September 2015 at 02:50 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.
