Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 16 July 2013 at 03:18.

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 ♑ Capricorn

Moon is passing about ∠11° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1888".

Buck Moon after 1 day

Next Full Moon is the Buck Moon of July 2013 after 1 day on 22 July 2013 at 18:15.

Upcoming main Moon phases

  • Full Moon in Capricorn ♑ on 22 July 2013 at 18:15

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 167 / 1120

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 167 of Meeus index or 1120 from Brown series.

Synodic month length 29.61 days

The length of the lunation is 29 days, 14 hours and 36 minutes. It is 51 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 52 minutes longer than the mean synodic month length. It is 5 hours and 11 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠191.6°

At the beginning of the lunation cycle the true anomaly is ∠191.6°. At the beginning of next synodic month the true anomaly is going to be ∠216.9°.

Moon at perigee

Moon is at perigee at 20:27. It is 14 days after previous apogee on 7 July 2013 at 00:36 in ♋ Cancer. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 12 days, until point of next apogee on 3 August 2013 at 08:53 in ♋ Cancer.

Previous apogeeNext apogee

Distance to Moon 358 402 km

This perigee Moon is 358 402 km (222 701 mi) away from Earth. It is 4 106 km closer than the mean perigee distance, but it is still 11 954 km further than the closest perigee of 21st century.

Moon after ascending node

3 days after ascending node on 17 July 2013 at 14:58 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 30 July 2013 at 05:50 in ♉ Taurus.

Previous nodeNext node

Draconic month

3 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

1 day since the previous standstill on 20 July 2013 at 03:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.097°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠20.025° at the point of next northern standstill on 2 August 2013 at 09:24 in ♊ Gemini.

Syzygy in 1 day

In 1 day on 22 July 2013 at 18:15 in ♑ Capricorn the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
