Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 18 May 2013 at 04:35.

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 ♏ Scorpio

Moon is passing about ∠9° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1938"

Lunar disc appears visually 2.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1895".

Flower Moon after 1 day

Next Full Moon is the Flower Moon of May 2013 after 1 day on 25 May 2013 at 04:25.

Upcoming main Moon phases

  • Full Moon in Sagittarius ♐ on 25 May 2013 at 04:25
  • Last Quarter in Pisces ♓ on 31 May 2013 at 18:58
  • New Moon in Gemini ♊ on 8 June 2013 at 15:56
  • First Quarter in Virgo ♍ on 16 June 2013 at 17:24

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 165 / 1118

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 165 of Meeus index or 1118 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.64 days

The length of the lunation is 29 days, 15 hours and 28 minutes. This is the year's longest synodic month of 2013. It is 10 minutes longer than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 2 hours and 44 minutes longer than the mean synodic month length. It is 4 hours and 19 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠143.3°

At the beginning of the lunation cycle the true anomaly is ∠143.3°. At the beginning of next synodic month the true anomaly is going to be ∠168.8°.

Moon before apogee

9 days after point of apogee on 13 May 2013 at 13:31 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 26 May 2013 at 01:45 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 369 858 km

The Moon is 369 858 km (229 819 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 358 375 km (222 684 mi).

Moon before ascending node

13 days after descending node on 9 May 2013 at 19:12 in ♉ Taurus. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 24 May 2013 at 00:40 in ♏ Scorpio.

Previous nodeNext node

Draconic month

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

Moon before southern standstill

10 days since the previous standstill on 12 May 2013 at 12:30 in ♊ Gemini when the Moon has reached North declination of ∠20.170°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-20.182° at the point of next southern standstill on 26 May 2013 at 04:47 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 1 day

In 1 day on 25 May 2013 at 04:25 in ♐ Sagittarius 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.
