Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♉ Taurus

Moon is leaving the last ∠2° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1900".

Harvest Moon after 22 days

Next Full Moon is the Harvest Moon of September 2021 after 22 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 267 / 1220

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 267 of Meeus index or 1220 from Brown series.

Synodic month length 29.46 days

The length of the lunation is 29 days, 11 hours and 2 minutes. It is 48 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠264.3°

At the beginning of the lunation cycle the true anomaly is ∠264.3°. At the beginning of next synodic month the true anomaly is going to be ∠297.8°.

Moon before perigee

12 days after point of perigee on 17 August 2021 at 09:23 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 30 August 2021 at 02:22 in ♊ Gemini.

Distance to Moon 405 337 km

The Moon is 405 337 km (251 865 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 100 km (251 096 mi).

Moon before ascending node

12 days after descending node on 16 August 2021 at 16:04 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 30 August 2021 at 05:13 in ♊ Gemini.

Draconic month

26 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 before northern standstill

10 days since the previous standstill on 18 August 2021 at 22:24 in ♑ Capricorn when the Moon has reached South declination of ∠-25.761°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠25.868° at the point of next northern standstill on 2 September 2021 at 00:23 in ♋ Cancer.

Syzygy in 8 days

In 8 days on 7 September 2021 at 00:52 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
