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 1084 / 2037

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 1084 of Meeus index or 2037 from Brown series.

Synodic month length 29.57 days

Length of current 1084 lunation is 29 days, 13 hours and 39 minutes. It is 3 hours and 4 minutes shorter than next lunation 1085 length.

Lunation length longer than mean

Length of current synodic month is 55 minutes longer than the mean length of synodic month, but it is still 6 hours and 8 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠95.4°

This New Moon true anomaly is ∠95.4°. At beginning of next synodic month true anomaly will be ∠129.7°. 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

2 days after point of perigee on 15 September 2087 at 08:02 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 1 October 2087 at 05:52 in ♏ Scorpio.

Distance to Moon 363 456 km

Moon is 363 456 km (225 841 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 405 480 km (251 954 mi).

Moon after descending node

1 day after its descending node on 16 September 2087 at 15:01 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 30 September 2087 at 07:30 in ♏ Scorpio.

Moon before northern standstill

11 days after previous South standstill on 5 September 2087 at 19:29 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.343°. Next day the lunar orbit moves northward to face North declination of ∠20.239° in the next northern standstill on 18 September 2087 at 21:42 in ♊ Gemini.

Syzygy in 9 days

After 9 days on 26 September 2087 at 18:47 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
