Moon phase and lunation details
3 days after Full Moon
Previous main lunar phase is the Full Moon before 3 days on 30 September 2031 at 18:58.
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 ♉ Taurus
Moon is leaving the last ∠3° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.
Apparent angular diameter ∠1817"
Lunar disc appears visually 5.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1817" and ∠1918".
Harvest Moon before 3 days
Next Full Moon is the Hunter Moon of October 2031 after 25 days on 30 October 2031 at 07:33.
Upcoming main Moon phases
- Last Quarter in Cancer ♋ on 8 October 2031 at 10:50
- New Moon in Libra ♎ on 16 October 2031 at 08:21
- First Quarter in Capricorn ♑ on 23 October 2031 at 07:36
- Full Moon in Taurus ♉ on 30 October 2031 at 07:33
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 392 / 1345
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 392 of Meeus index or 1345 from Brown series.
Synodic month length 29.57 days
The length of the lunation is 29 days, 13 hours and 34 minutes. It is 45 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 longer than mean
The length of the current synodic month is 50 minutes longer than the mean synodic month length. It is 6 hours and 13 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠245.2°
At the beginning of the lunation cycle the true anomaly is ∠245.2°. At the beginning of next synodic month the true anomaly is going to be ∠281.8°.
Moon before perigee
7 days after point of perigee on 27 September 2031 at 07:09 in ♒ Aquarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next apogee on 9 October 2031 at 06:23 in ♋ Cancer.
Distance to Moon 394 493 km
The Moon is 394 493 km (245 127 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 365 km (251 261 mi).
Moon after descending node
1 day after descending node on 3 October 2031 at 22:04 in ♉ Taurus. The Moon is located south of the ecliptic over the following 13 days, until the lunar orbit crosses from South to North in ascending node on 18 October 2031 at 06:54 in ♏ Scorpio.
Draconic month
13 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the middle to the last part of the cycle.
Moon before northern standstill
11 days since the previous standstill on 23 September 2031 at 05:46 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.501°, the lunar orbit is extending northward over the next day to face maximum declination of ∠20.418° at the point of next northern standstill on 6 October 2031 at 07:31 in ♊ Gemini.
Syzygy in 11 days
In 11 days on 16 October 2031 at 08:21 in ♎ Libra 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.
