Upcoming main Moon phases
- Last Quarter in Taurus ♉ on 28 August 2051 at 17:29
- New Moon in Virgo ♍ on 5 September 2051 at 04:33
- First Quarter in Sagittarius ♐ on 13 September 2051 at 09:20

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 638 / 1591
The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 638 of Meeus index or 1591 from Brown series.
Synodic month length 29.56 days
Length of current 638 lunation is 29 days, 13 hours and 28 minutes. It is 2 hours and 46 minutes shorter than next lunation 639 length.
Lunation length longer than mean
Length of current synodic month is 44 minutes longer than the mean length of synodic month, but it is still 6 hours and 19 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠104.1°
This New Moon true anomaly is ∠104.1°. At beginning of next synodic month true anomaly will be ∠137°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon in perigee
Moon is reaching point of perigee on this date at 08:43, this is 11 days after last apogee on 12 August 2051 at 11:22 in ♎ Libra. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 15 days ahead, until it will get to the point of next apogee on 9 September 2051 at 04:18 in ♏ Scorpio.
Distance to Moon 363 298 km
This perigee Moon is 363 298 km (225 743 mi) away from Earth. It is 790 km closer than the mean perigee distance, but it is still 7 058 km farther than the closest perigee of 21st century.
Moon before descending node
12 days after its ascending node on 12 August 2051 at 11:44 in ♎ Libra, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 25 August 2051 at 20:56 in ♈ Aries.
Draconic month
12 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the beginning to the first part of it.
Moon before northern standstill
7 days after previous South standstill on 17 August 2051 at 06:45 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.946°. Next 5 days the lunar orbit moves northward to face North declination of ∠18.858° in the next northern standstill on 30 August 2051 at 01:37 in ♊ Gemini.
Syzygy in 11 days
After 11 days on 5 September 2051 at 04:33 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
