Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 13 September 2021 at 20:39.

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 in ♓ Pisces

Moon is passing about ∠9° of ♓ Pisces tropical zodiac sector.

Apparent angular diameter ∠1866"

Lunar disc appears visually 2.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1866" and ∠1911".

Harvest Moon after 1 day

Next Full Moon is the Harvest Moon of September 2021 after 1 day on 20 September 2021 at 23:55.

Upcoming main Moon phases

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 268 / 1221

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 268 of Meeus index or 1221 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.43 days

Length of current 268 lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than next lunation 269 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 30 minutes shorter than the mean length of synodic month, but it is still 3 hours and 39 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠297.8°

This lunation true anomaly is ∠297.8°. At the beginning of next synodic month true anomaly will be ∠323.3°. 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

8 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 384 112 km

Moon is 384 112 km (238 676 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 404 641 km (251 432 mi).

Moon after descending node

6 days after its descending node on 12 September 2021 at 16:35 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.

Draconic month

20 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

4 days after previous South standstill on 15 September 2021 at 03:48 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.980°. Next 9 days the lunar orbit moves northward to face North declination of ∠26.109° in the next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.

Syzygy in 1 day

After 1 day on 20 September 2021 at 23:55 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
