Moon phase and lunation details
3 days after Full Moon
Previous main lunar phase is the Full Moon before 3 days on 22 August 2021 at 12:02.
Moonrise and moonset
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon in ♈ Aries
Moon is passing about ∠22° of ♈ Aries tropical zodiac sector.
Apparent angular diameter ∠1795"
Lunar disc appears visually 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1795" and ∠1899".
Sturgeon Moon before 3 days
Next Full Moon is the Harvest Moon of September 2021 after 25 days on 20 September 2021 at 23:55.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 30 August 2021 at 07:13
- New Moon in Virgo ♍ on 7 September 2021 at 00:52
- First Quarter in Sagittarius ♐ on 13 September 2021 at 20:39

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 18 days old. Earth's natural satellite is moving from the middle to 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
9 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 3 days, until the Moon reaches the point of next apogee on 30 August 2021 at 02:22 in ♊ Gemini.
Distance to Moon 399 300 km
The Moon is 399 300 km (248 114 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 100 km (251 096 mi).
Moon before ascending node
9 days after descending node on 16 August 2021 at 16:04 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 30 August 2021 at 05:13 in ♊ Gemini.
Draconic month
23 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
7 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 6 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 11 days
In 11 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.
