Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 27 July 2018 at 20:20.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♓ Pisces

Moon is passing about ∠18° of ♓ Pisces tropical zodiac sector.

Buck Moon before 3 days

Next Full Moon is the Sturgeon Moon of August 2018 after 25 days on 26 August 2018 at 11:56.

Upcoming main Moon phases

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 229 / 1182

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 229 of Meeus index or 1182 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.3 days

Length of current 229 lunation is 29 days, 7 hours and 10 minutes. It is 54 minutes shorter than next lunation 230 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 34 minutes shorter than the mean length of synodic month, but it is still 35 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠356°

This New Moon true anomaly is ∠356°. At beginning of next synodic month true anomaly will be ∠11.2°. 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 after apogee

4 days after point of apogee on 27 July 2018 at 05:44 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 10 August 2018 at 18:05 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 397 728 km

Moon is 397 728 km (247 137 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 358 083 km (222 502 mi).

Moon after descending node

3 days after its descending node on 27 July 2018 at 22:40 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 10 August 2018 at 13:40 in ♋ Cancer.

Moon after southern standstill

5 days after previous South standstill on 25 July 2018 at 20:55 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.755°. Next 8 days the lunar orbit moves northward to face North declination of ∠20.757° in the next northern standstill on 8 August 2018 at 22:33 in ♋ Cancer.

Syzygy in 10 days

After 10 days on 11 August 2018 at 09:58 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
