Moon phase and lunation details
Moonrise and moonset
Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon in ♓ Pisces
Moon is leaving the last ∠1° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Apparent angular diameter ∠1960"
Lunar disc appears visually 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1960" and ∠1911".

Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 639 / 1592
The Moon is 15 days old. Earth's natural satellite is moving through the middle 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 before apogee
11 days after point of apogee on 9 September 2051 at 04:18 in ♏ Scorpio. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 21 September 2051 at 12:20 in ♈ Aries.
Distance to Moon 365 661 km
The Moon is 365 661 km (227 211 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 358 920 km (223 023 mi).
Moon before descending node
11 days after ascending node on 8 September 2051 at 15:18 in ♎ Libra. 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 22 September 2051 at 03:59 in ♈ Aries.
Draconic month
11 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the beginning to the first part of the cycle.
Moon before northern standstill
6 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 5 days to face maximum declination of ∠18.704° at the point of next northern standstill on 26 September 2051 at 07:36 in ♊ Gemini.
Sun-Earth-Moon syzygy
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
