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 in ♒ Aquarius

Moon is passing about ∠16° of ♒ Aquarius tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 28 September 2017 at 02:54.

Hunter Moon after 4 days

Next Full Moon is the Hunter Moon of October 2017 after 4 days on 5 October 2017 at 18:40.

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 ∠1806"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1806" and ∠1917".

Lunation 219 / 1172

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 219 of Meeus index or 1172 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 42 minutes and it is 2 hours and 48 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 longer than mean

The length of the current synodic month is 58 minutes longer than the mean synodic month length. It is 6 hours and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠79°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠79° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠114.6°.

Moon after apogee

4 days since point of apogee on 27 September 2017 at 06:49 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 9 October 2017 at 05:51 in ♊ Gemini.

Distance to Moon 396 882 km

The Moon is 396 882 km (246 611 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 366 858 km (227 955 mi).

Moon before descending node

13 days after ascending node on 17 September 2017 at 18:28 in ♌ Leo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 2 October 2017 at 02:05 in ♒ Aquarius.

Moon after southern standstill

3 days since the last southern standstill on 28 September 2017 at 10:06 in ♑ Capricorn when the Moon has reached South declination of ∠-19.516° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠19.616° at the point of next northern standstill on 11 October 2017 at 18:21 in ♋ Cancer.

Draconic month

13 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the first to the middle part of the lunar cycle.

Syzygy in 4 days

In 4 days on 5 October 2017 at 18:40 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.
