Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 20 October 2021 at 14:57.

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 ♋ Cancer

Moon is passing about ∠19° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1789"

Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1931".

Hunter Moon before 6 days

Next Full Moon is the Beaver Moon of November 2021 after 22 days on 19 November 2021 at 08:58.

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 269 / 1222

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.42 days

Length of current 269 lunation is 29 days, 10 hours and 9 minutes. This is the year's shortest synodic month of 2021. It is 19 minutes shorter than next lunation 270 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 35 minutes shorter than the mean length of synodic month, but it is still 3 hours and 34 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠323.3°

This lunation true anomaly is ∠323.3°. At the beginning of next synodic month true anomaly will be ∠342.3°. 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 after apogee

2 days after point of apogee on 24 October 2021 at 15:30 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 5 November 2021 at 22:23 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 400 550 km

Moon is 400 550 km (248 890 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 358 845 km (222 976 mi).

Moon after ascending node

4 days after its ascending node on 23 October 2021 at 11:47 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 9 days, until it will cross the ecliptic from North to South in descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.

Draconic month

4 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the beginning to the first part of it.

Moon after northern standstill

1 day after previous North standstill on 26 October 2021 at 16:04 in ♋ Cancer, when Moon has reached northern declination of ∠26.291°. Next 12 days the lunar orbit moves southward to face South declination of ∠-26.328° in the next southern standstill on 8 November 2021 at 16:27 in ♑ Capricorn.

Syzygy in 8 days

After 8 days on 4 November 2021 at 21:15 in ♏ Scorpio, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
