Moon phase and lunation details
1 day after Full Moon
Previous main lunar phase is the Full Moon before 1 day on 6 September 2017 at 07:03.
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 is entering ♓ Pisces
Moon is passing first ∠0° of ♓ Pisces tropical zodiac sector.
Apparent angular diameter ∠1883"
Lunar disc appears visually 1.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1883" and ∠1904".
Harvest Moon before 1 day
Next Full Moon is the Hunter Moon of October 2017 after 28 days on 5 October 2017 at 18:40.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 13 September 2017 at 06:25
- New Moon in Virgo ♍ on 20 September 2017 at 05:30
- First Quarter in Capricorn ♑ on 28 September 2017 at 02:54

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 218 / 1171
The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last 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 before apogee
8 days after point of apogee on 30 August 2017 at 11:25 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
Distance to Moon 380 602 km
The Moon is 380 602 km (236 495 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 369 856 km (229 818 mi).
Moon after descending node
2 days after descending node on 4 September 2017 at 18:41 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 17 September 2017 at 18:28 in ♌ Leo.
Draconic month
17 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.
Moon after southern standstill
6 days since the previous standstill on 1 September 2017 at 02:03 in ♑ Capricorn when the Moon has reached South declination of ∠-19.393°, the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠19.438° at the point of next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.
Syzygy in 12 days
In 12 days on 20 September 2017 at 05:30 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.
