Moon phase and lunation details

4 days after First Quarter

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 ♎ Libra

Moon is leaving the last ∠3° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Apparent angular diameter ∠1966"

Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1898".

Flower Moon after 1 day

Next Full Moon is the Flower Moon of May 2011 after 1 day on 17 May 2011 at 11:09.

Upcoming main Moon phases

  • Full Moon in Scorpio ♏ on 17 May 2011 at 11:09
  • Last Quarter in Aquarius ♒ on 24 May 2011 at 18:52
  • New Moon in Gemini ♊ on 1 June 2011 at 21:03
  • First Quarter in Virgo ♍ on 9 June 2011 at 02:11

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 140 / 1093

The Moon is 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

Length of current 140 lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than next lunation 141 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 28 minutes longer than the mean length of synodic month, but it is still 5 hours and 35 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠216.7°

This lunation true anomaly is ∠216.7°. At the beginning of next synodic month true anomaly will be ∠248.4°. 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 11:18, this is 15 days after last apogee on 29 April 2011 at 18:02 in ♓ Pisces. 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 27 May 2011 at 09:58 in ♈ Aries.

Previous apogeeNext apogee

Distance to Moon 362 133 km

This perigee Moon is 362 133 km (225 019 mi) away from Earth. It is 375 km closer than the mean perigee distance, but it is still 8 223 km farther than the closest perigee of 21st century.

Moon before ascending node

8 days after its descending node on 6 May 2011 at 14:54 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

23 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.

Moon before southern standstill

9 days after previous North standstill on 6 May 2011 at 03:54 in ♊ Gemini, when Moon has reached northern declination of ∠23.421°. Next 3 days the lunar orbit moves southward to face South declination of ∠-23.403° in the next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.

Syzygy in 1 day

After 1 day on 17 May 2011 at 11:09 in ♏ Scorpio, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
