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 ♑ Capricorn

Moon is passing about ∠25° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1942"

Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1924".

Hunter Moon after 7 days

Next Full Moon is the Hunter Moon of October 2021 after 7 days on 20 October 2021 at 14:57.

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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.

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 perigee

4 days after point of perigee on 8 October 2021 at 17:28 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 24 October 2021 at 15:30 in ♊ Gemini.

Distance to Moon 369 064 km

Moon is 369 064 km (229 326 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 405 616 km (252 038 mi).

Moon after descending node

3 days after its descending node on 9 October 2021 at 19:35 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 23 October 2021 at 11:47 in ♊ Gemini.

Draconic month

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

Moon after southern standstill

1 day after previous South standstill on 12 October 2021 at 09:09 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.204°. Next 13 days the lunar orbit moves northward to face North declination of ∠26.291° in the next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.

Syzygy in 7 days

After 7 days on 20 October 2021 at 14:57 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
