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 in ♒ Aquarius

Moon is passing about ∠12° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1910"

Lunar disc appears visually 1.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1910" and ∠1933".

Beaver Moon after 6 days

Next Full Moon is the Beaver Moon of November 2033 after 6 days on 6 November 2033 at 20:32.

Upcoming main Moon phases

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 418 / 1371

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 418 of Meeus index or 1371 from Brown series.

Synodic month length 29.76 days

Length of current 418 lunation is 29 days, 18 hours and 11 minutes. This is the year's longest synodic month of 2033. It is 1 hour and 4 minutes longer than next lunation 419 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 27 minutes longer than the mean length of synodic month, but it is still 1 hour and 36 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠190.3°

This lunation true anomaly is ∠190.3°. At the beginning of next synodic month true anomaly will be ∠217.2°. 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 before perigee

9 days after point of apogee on 22 October 2033 at 03:15 in ♎ Libra. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 5 November 2033 at 23:57 in ♈ Aries.

Distance to Moon 375 270 km

Moon is 375 270 km (233 182 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 102 km (222 514 mi).

Moon before descending node

9 days after its ascending node on 21 October 2033 at 19:04 in ♎ Libra, the Moon is following the northern part of its orbit for the next 4 days, until it will cross the ecliptic from North to South in descending node on 4 November 2033 at 16:35 in ♈ Aries.

Draconic month

9 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the beginning to the first part of it.

Moon after southern standstill

3 days after previous South standstill on 27 October 2033 at 23:48 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.327°. Next 9 days the lunar orbit moves northward to face North declination of ∠18.369° in the next northern standstill on 9 November 2033 at 16:57 in ♊ Gemini.

Syzygy in 6 days

After 6 days on 6 November 2033 at 20:32 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
