Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 26 October 2013 at 23:41.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon is entering ♍ Virgo

Moon is passing first ∠0° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1843"

Lunar disc appears visually 4.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1843" and ∠1933".

Beaver Moon after 17 days

Next Full Moon is the Beaver Moon of November 2013 after 17 days on 17 November 2013 at 15:16.

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 170 / 1123

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 170 of Meeus index or 1123 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.51 days

Length of current 170 lunation is 29 days, 12 hours and 15 minutes. It is 43 minutes longer than next lunation 171 length.

Lunation length shorter than mean

Length of current synodic month is 29 minutes shorter than the mean length of synodic month, but it is still 5 hours and 40 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠285.3°

This lunation true anomaly is ∠285.3°. At the beginning of next synodic month true anomaly will be ∠315°. 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

5 days after point of apogee on 25 October 2013 at 14:25 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 6 November 2013 at 09:28 in ♐ Sagittarius.

Distance to Moon 389 012 km

Moon is 389 012 km (241 721 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 365 362 km (227 025 mi).

Moon before ascending node

11 days after its descending node on 19 October 2013 at 21:47 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 3 November 2013 at 06:52 in ♏ Scorpio.

Moon before southern standstill

8 days after previous North standstill on 23 October 2013 at 09:13 in ♊ Gemini, when Moon has reached northern declination of ∠19.509°. Next 5 days the lunar orbit moves southward to face South declination of ∠-19.511° in the next southern standstill on 6 November 2013 at 06:43 in ♐ Sagittarius.

Syzygy in 3 days

After 3 days on 3 November 2013 at 12:50 in ♏ Scorpio, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
