Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 14 May 2033 at 10:43.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♒ Aquarius

Moon is passing about ∠13° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1938"

Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1896".

Flower Moon before 6 days

Next Full Moon is the Strawberry Moon of June 2033 after 23 days on 12 June 2033 at 23:19.

Upcoming main Moon phases

  • Last Quarter in Aquarius ♒ on 21 May 2033 at 18:29
  • New Moon in Gemini ♊ on 28 May 2033 at 11:36
  • First Quarter in Virgo ♍ on 4 June 2033 at 23:39
  • Full Moon in Sagittarius ♐ on 12 June 2033 at 23:19

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 412 / 1365

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 412 of Meeus index or 1365 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 50 minutes. This is the year's shortest synodic month of 2033. It is 40 minutes shorter 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 shorter than mean

The length of the current synodic month is 3 hours and 54 minutes shorter than the mean synodic month length. It is 2 hours and 15 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠25.1°

At the beginning of the lunation cycle the true anomaly is ∠25.1°. At the beginning of next synodic month the true anomaly is going to be ∠46°.

Moon before apogee

10 days after point of apogee on 9 May 2033 at 16:25 in ♍ Virgo. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 25 May 2033 at 13:01 in ♈ Aries.

Previous apogeeNext perigee

Distance to Moon 369 871 km

The Moon is 369 871 km (229 827 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 365 415 km (227 058 mi).

Moon before descending node

8 days after ascending node on 11 May 2033 at 17:56 in ♎ Libra. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 25 May 2033 at 05:37 in ♈ Aries.

Previous nodeNext node

Draconic month

8 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

3 days since the previous standstill on 16 May 2033 at 20:25 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.668°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠18.697° at the point of next northern standstill on 29 May 2033 at 17:10 in ♊ Gemini.

Syzygy in 7 days

In 7 days on 28 May 2033 at 11:36 in ♊ Gemini the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
