Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 14 August 2013 at 10:56.

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 ♒ Aquarius

Moon is passing about ∠5° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1962"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1962" and ∠1896".

Sturgeon Moon after 1 day

Next Full Moon is the Sturgeon Moon of August 2013 after 1 day on 21 August 2013 at 01:45.

Upcoming main Moon phases

Moderate tide

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 168 / 1121

The Moon is 13 days young. Earth's natural satellite is moving from the first to the middle 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 in perigee

Moon is reaching point of perigee on this date at 01:26, this is 15 days after last apogee on 3 August 2013 at 08:53 in ♋ Cancer. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 11 days ahead, until it will get to the point of next apogee on 30 August 2013 at 23:46 in ♋ Cancer.

Previous apogeeNext apogee

Distance to Moon 362 265 km

This perigee Moon is 362 265 km (225 101 mi) away from Earth. It is 243 km closer than the mean perigee distance, but it is still 8 091 km farther than the closest perigee of 21st century.

Moon after ascending node

5 days after its ascending node on 13 August 2013 at 16:20 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 26 August 2013 at 08:19 in ♉ Taurus.

Draconic month

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

Moon after southern standstill

2 days after previous South standstill on 16 August 2013 at 12:06 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.906°. Next 10 days the lunar orbit moves northward to face North declination of ∠19.801° in the next northern standstill on 29 August 2013 at 17:03 in ♊ Gemini.

Syzygy in 1 day

After 1 day on 21 August 2013 at 01:45 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
