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

The length of the lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠297.8°

At the beginning of the lunation cycle the true anomaly is ∠297.8°. At the beginning of next synodic month the true anomaly is going to be ∠323.3°.

Moon before perigee

8 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 384 112 km

The Moon is 384 112 km (238 676 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 404 641 km (251 432 mi).

Moon after descending node

6 days after descending node on 12 September 2021 at 16:35 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 6 days, until the lunar orbit crosses from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.

Draconic month

20 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.

Moon after southern standstill

4 days since the previous standstill on 15 September 2021 at 03:48 in ♑ Capricorn when the Moon has reached South declination of ∠-25.980°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠26.109° at the point of next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.

Syzygy in 1 day

In 1 day on 20 September 2021 at 23:55 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
