Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 18 August 2018 at 07:49.

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.

Moon in ♐ Sagittarius

Moon is passing about ∠22° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1790"

Lunar disc appears visually 5.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1790" and ∠1897".

Sturgeon Moon after 5 days

Next Full Moon is the Sturgeon Moon of August 2018 after 5 days on 26 August 2018 at 11:56.

Upcoming main Moon phases

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.

Lunation 230 / 1183

The Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 230 of Meeus index or 1183 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.34 days

Length of current 230 lunation is 29 days, 8 hours and 4 minutes. It is 1 hour and 41 minutes shorter than next lunation 231 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 40 minutes shorter than the mean length of synodic month, but it is still 1 hour and 29 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠11.2°

This New Moon true anomaly is ∠11.2°. At beginning of next synodic month true anomaly will be ∠28°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before apogee

9 days after point of perigee on 10 August 2018 at 18:05 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 23 August 2018 at 11:23 in ♑ Capricorn.

Distance to Moon 400 387 km

Moon is 400 387 km (248 789 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 405 744 km (252 118 mi).

Moon before descending node

9 days after its ascending node on 10 August 2018 at 13:40 in ♋ Cancer, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 24 August 2018 at 04:51 in ♒ Aquarius.

Moon before southern standstill

11 days after previous North standstill on 8 August 2018 at 22:33 in ♋ Cancer, when Moon has reached northern declination of ∠20.757°. Next day the lunar orbit moves southward to face South declination of ∠-20.773° in the next southern standstill on 22 August 2018 at 02:58 in ♑ Capricorn.

Syzygy in 5 days

After 5 days on 26 August 2018 at 11:56 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
