Moon phase and lunation details

5 days after New Moon

Previous main lunar phase is the New Moon before 5 days on 7 September 2021 at 00:52.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon is entering ♐ Sagittarius

Moon is passing first ∠2° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1907".

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2021 after 8 days on 20 September 2021 at 23:55.

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 268 / 1221

The Moon is 6 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 268 of Meeus index or 1221 from Brown series.

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 after perigee

1 day 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 14 days, until the Moon reaches the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.

Distance to Moon 363 348 km

The Moon is 363 348 km (225 774 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 404 641 km (251 432 mi).

Moon in descending node

Moon is in descending node in ♏ Scorpio at 16:35 crossing the ecliptic from North to South to meet ascending node 13 days later on 26 September 2021 at 07:33 in ♊ Gemini.

Moon before southern standstill

10 days since the previous standstill on 2 September 2021 at 00:23 in ♋ Cancer when the Moon has reached North declination of ∠25.868°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-25.980° at the point of next southern standstill on 15 September 2021 at 03:48 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 8 days

In 8 days 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.
