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 20 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
Length of current 639 lunation is 29 days, 16 hours and 14 minutes. It is 1 hour and 58 minutes shorter than next lunation 640 length.
Lunation length longer than mean
Length of current synodic month is 3 hours and 29 minutes longer than the mean length of synodic month, but it is still 3 hours and 33 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠137°
This New Moon true anomaly is ∠137°. At beginning of next synodic month true anomaly will be ∠163.9°. 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 after perigee
3 days after point of perigee on 21 September 2051 at 12:20 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 6 October 2051 at 15:34 in ♎ Libra.
Distance to Moon 368 646 km
Moon is 368 646 km (229 066 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 406 415 km (252 535 mi).
Moon after descending node
3 days after its descending node on 22 September 2051 at 03:59 in ♈ Aries, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 5 October 2051 at 20:55 in ♎ Libra.
Draconic month
16 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the second to the final part of it.
Moon before northern standstill
11 days after previous South standstill on 13 September 2051 at 15:30 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.758°. Next day the lunar orbit moves northward to face North declination of ∠18.704° in the next northern standstill on 26 September 2051 at 07:36 in ♊ Gemini.
Syzygy in 9 days
After 9 days on 4 October 2051 at 20:47 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
