Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is entering ♍ Virgo

Moon is passing first ∠2° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1966"

Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1895".

Flower Moon after 7 days

Next Full Moon is the Flower Moon of May 2045 after 7 days on 30 May 2045 at 17:52.

Upcoming main Moon phases

  • Full Moon in Sagittarius ♐ on 30 May 2045 at 17:52
  • Last Quarter in Pisces ♓ on 7 June 2045 at 20:23
  • New Moon in Gemini ♊ on 15 June 2045 at 03:05

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 561 / 1514

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 561 of Meeus index or 1514 from Brown series.

Synodic month length 29.36 days

The length of the lunation is 29 days, 8 hours and 38 minutes. It is 1 hour and 14 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 shorter than mean

The length of the current synodic month is 4 hours and 6 minutes shorter than the mean synodic month length. It is 2 hours and 3 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠305.3°

At the beginning of the lunation cycle the true anomaly is ∠305.3°. At the beginning of next synodic month the true anomaly is going to be ∠328°.

Moon after perigee

3 days after point of perigee on 20 May 2045 at 10:22 in ♋ Cancer. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 5 June 2045 at 03:25 in ♒ Aquarius.

Distance to Moon 364 650 km

The Moon is 364 650 km (226 583 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 694 km (251 465 mi).

Moon in descending node

Moon is in descending node in ♌ Leo at 02:17 crossing the ecliptic from North to South to meet ascending node 13 days later on 5 June 2045 at 23:31 in ♒ Aquarius.

Draconic month

13 days since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

4 days since the previous standstill on 18 May 2045 at 18:47 in ♊ Gemini when the Moon has reached North declination of ∠27.745°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-27.697° at the point of next southern standstill on 31 May 2045 at 22:23 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 30 May 2045 at 17:52 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.
