Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 19 September 2013 at 11:13.

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 ♉ Taurus

Moon is passing about ∠7° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1826"

Lunar disc appears visually 4.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1826" and ∠1912".

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2013 after 26 days on 18 October 2013 at 23:38.

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 169 / 1122

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 169 of Meeus index or 1122 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.54 days

Length of current 169 lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer than next lunation 170 length.

Lunation length longer than mean

Length of current synodic month is 14 minutes longer than the mean length of synodic month, but it is still 6 hours and 49 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠249.2°

This lunation true anomaly is ∠249.2°. At the beginning of next synodic month true anomaly will be ∠285.3°. 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 apogee

6 days after point of perigee on 15 September 2013 at 16:34 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 27 September 2013 at 18:17 in ♋ Cancer.

Distance to Moon 392 461 km

Moon is 392 461 km (243 864 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 404 309 km (251 226 mi).

Moon in descending node

Moon is in descending node in ♉ Taurus at 13:48 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 14 days to meet ascending node on 6 October 2013 at 22:08 in ♏ Scorpio.

Moon before northern standstill

9 days after previous South standstill on 12 September 2013 at 18:30 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.685°. Next 3 days the lunar orbit moves northward to face North declination of ∠19.599° in the next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.

Syzygy in 12 days

After 12 days on 5 October 2013 at 00:35 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
