Moon phase and lunation details
Moonrise and moonset
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon in ♐ Sagittarius
Moon is passing about ∠20° of ♐ Sagittarius tropical zodiac sector.
Apparent angular diameter ∠1768"
Lunar disc appears visually 7.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1901".
Harvest Moon after 6 days
Next Full Moon is the Harvest Moon of September 2017 after 6 days on 6 September 2017 at 07:03.
Upcoming main Moon phases
- Full Moon in Pisces ♓ on 6 September 2017 at 07:03
- Last Quarter in Gemini ♊ on 13 September 2017 at 06:25
- New Moon in Virgo ♍ on 20 September 2017 at 05:30

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 218 / 1171
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 218 of Meeus index or 1171 from Brown series.
Synodic month length 29.46 days
The length of the lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
Lunation length shorter than mean
The length of the current synodic month is 1 hour and 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠49.5°
At the beginning of the lunation cycle the true anomaly is ∠49.5°. At the beginning of next synodic month the true anomaly is going to be ∠79°.
Moon at apogee
Moon is at apogee at 11:25. It is 11 days after previous perigee on 18 August 2017 at 13:14 in ♋ Cancer. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 14 days, until point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
Distance to Moon 404 307 km
This apogee Moon is 404 307 km (251 225 mi) away from Earth. This is the year's closest apogee of 2017. It is 1 101 km further than the mean apogee distance, but it is still 256 km closer than the farthest apogee of 21st century.
Moon before descending node
9 days after ascending node on 21 August 2017 at 10:34 in ♌ Leo. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.
Draconic month
9 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the beginning to the first part of the cycle.
Moon before southern standstill
12 days since the previous standstill on 18 August 2017 at 06:50 in ♋ Cancer when the Moon has reached North declination of ∠19.381°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
Syzygy in 6 days
In 6 days on 6 September 2017 at 07:03 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.
