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 is entering ♑ Capricorn
Moon is passing first ∠0° of ♑ Capricorn tropical zodiac sector.
Apparent angular diameter ∠1782"
Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1782" and ∠1931".
Beaver Moon after 7 days
Next Full Moon is the Beaver Moon of November 2017 after 7 days on 4 November 2017 at 05:23.
Upcoming main Moon phases
- Full Moon in Taurus ♉ on 4 November 2017 at 05:23
- Last Quarter in Leo ♌ on 10 November 2017 at 20:37
- New Moon in Scorpio ♏ on 18 November 2017 at 11:42
- First Quarter in Aquarius ♒ on 26 November 2017 at 17:03
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 220 / 1173
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 220 of Meeus index or 1173 from Brown series.
Synodic month length 29.69 days
The length of the lunation is 29 days, 16 hours and 30 minutes. It is 2 hours and 18 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 longer than mean
The length of the current synodic month is 3 hours and 46 minutes longer than the mean synodic month length. It is 3 hours and 17 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠114.6°
At the beginning of the lunation cycle the true anomaly is ∠114.6°. At the beginning of next synodic month the true anomaly is going to be ∠147°.
Moon after apogee
2 days after point of apogee on 25 October 2017 at 02:25 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 6 November 2017 at 00:09 in ♊ Gemini.
Distance to Moon 402 134 km
The Moon is 402 134 km (249 874 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 361 438 km (224 587 mi).
Moon before descending node
12 days after ascending node on 14 October 2017 at 22:10 in ♌ Leo. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 29 October 2017 at 06:41 in ♒ Aquarius.
Draconic month
12 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 after southern standstill
1 day since the previous standstill on 25 October 2017 at 18:13 in ♑ Capricorn when the Moon has reached South declination of ∠-19.741°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠19.848° at the point of next northern standstill on 8 November 2017 at 01:28 in ♋ Cancer.
Syzygy in 7 days
In 7 days on 4 November 2017 at 05:23 in ♉ Taurus 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.
