Moon phase and lunation details
4 days after Full Moon
Previous main lunar phase is the Full Moon before 4 days on 20 September 2051 at 10:11.
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 ∠2° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.
Apparent angular diameter ∠1960"
Lunar disc appears visually 2.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1960" and ∠1913".
Harvest Moon before 4 days
Next Full Moon is the Hunter Moon of October 2051 after 25 days on 19 October 2051 at 19:13.
Upcoming main Moon phases
- Last Quarter in Cancer ♋ on 27 September 2051 at 01:22
- New Moon in Libra ♎ on 4 October 2051 at 20:47
- First Quarter in Capricorn ♑ on 13 October 2051 at 00:12
- Full Moon in Aries ♈ on 19 October 2051 at 19:13
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 639 / 1592
The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 639 of Meeus index or 1592 from Brown series.
Synodic month length 29.68 days
The length of the lunation is 29 days, 16 hours and 14 minutes. It is 1 hour and 58 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 29 minutes longer than the mean synodic month length. It is 3 hours and 33 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠137°
At the beginning of the lunation cycle the true anomaly is ∠137°. At the beginning of next synodic month the true anomaly is going to be ∠163.9°.
Moon after perigee
2 days after point of perigee on 21 September 2051 at 12:20 in ♈ Aries. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 6 October 2051 at 15:34 in ♎ Libra.
Distance to Moon 365 774 km
The Moon is 365 774 km (227 281 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 406 415 km (252 535 mi).
Moon after descending node
2 days after descending node on 22 September 2051 at 03:59 in ♈ Aries. The Moon is located south of the ecliptic over the following 11 days, until the lunar orbit crosses from South to North in ascending node on 5 October 2051 at 20:55 in ♎ Libra.
Draconic month
15 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the second to the final part of the cycle.
Moon before northern standstill
10 days since the previous standstill on 13 September 2051 at 15:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.758°, the lunar orbit is extending northward over the next day to face maximum declination of ∠18.704° at the point of next northern standstill on 26 September 2051 at 07:36 in ♊ Gemini.
Syzygy in 10 days
In 10 days on 4 October 2051 at 20:47 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.
