Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 13 October 2021 at 03:25.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon is entering ♈ Aries

Moon is passing first ∠1° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1832"

Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1832" and ∠1926".

Hunter Moon after 2 days

Next Full Moon is the Hunter Moon of October 2021 after 2 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 13 days young. Earth's natural satellite is moving from the first to the middle 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 before apogee

9 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 6 days, until it get to the point of next apogee on 24 October 2021 at 15:30 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 391 157 km

Moon is 391 157 km (243 054 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 405 616 km (252 038 mi).

Moon before ascending node

8 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 4 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

22 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

6 days after previous South standstill on 12 October 2021 at 09:09 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.204°. Next 8 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 2 days

After 2 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.
