Moon phase and lunation details

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 6 August 2013 at 21:51.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♎ Libra

Moon is passing about ∠12° of ♎ Libra tropical zodiac sector.

Apparent angular diameter ∠1879"

Lunar disc appears visually 0.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1879" and ∠1893".

Sturgeon Moon after 9 days

Next Full Moon is the Sturgeon Moon of August 2013 after 9 days on 21 August 2013 at 01:45.

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 168 / 1121

The Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.57 days

Length of current 168 lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than next lunation 169 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 1 minute longer than the mean length of synodic month, but it is still 6 hours and 2 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠216.9°

This lunation true anomaly is ∠216.9°. At the beginning of next synodic month true anomaly will be ∠249.2°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before perigee

8 days after point of apogee on 3 August 2013 at 08:53 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 19 August 2013 at 01:26 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 381 482 km

Moon is 381 482 km (237 042 mi) away from Earth on this date. Moon moves closer next 7 days until perigee, when Earth-Moon distance will reach 362 265 km (225 101 mi).

Moon before ascending node

12 days after its descending node on 30 July 2013 at 05:50 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 13 August 2013 at 16:20 in ♏ Scorpio.

Draconic month

24 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.

Moon before southern standstill

9 days after previous North standstill on 2 August 2013 at 09:24 in ♊ Gemini, when Moon has reached northern declination of ∠20.025°. Next 5 days the lunar orbit moves southward to face South declination of ∠-19.906° in the next southern standstill on 16 August 2013 at 12:06 in ♐ Sagittarius.

Syzygy in 9 days

After 9 days on 21 August 2013 at 01:45 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
