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 1231 / 2184

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1231 of Meeus index or 2184 from Brown series.

Synodic month length 29.33 days

Length of current 1231 lunation is 29 days, 7 hours and 54 minutes. This is the year's shortest synodic month of 2099. It is 2 minutes shorter than next lunation 1232 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 50 minutes shorter than the mean length of synodic month, but it is still 1 hour and 19 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠320.2°

This lunation true anomaly is ∠320.2°. At the beginning of next synodic month true anomaly will be ∠339.4°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon in apogee

Moon is reaching point of apogee on this date at 08:15, this is 15 days after last perigee on 20 July 2099 at 12:45 in ♍ Virgo. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 17 August 2099 at 14:24 in ♍ Virgo.

Distance to Moon 405 336 km

This apogee Moon is 405 336 km (251 864 mi) away from Earth. It is 72 km farther than the mean apogee distance, but it is still 1 373 km closer than the farthest apogee of 21st century.

Moon in ascending node

Previous nodeNext node

New draconic month

At 03:00 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before northern standstill

7 days after previous South standstill on 28 July 2099 at 23:58 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.504°. Next 7 days the lunar orbit moves northward to face North declination of ∠28.579° in the next northern standstill on 12 August 2099 at 14:22 in ♊ Gemini.

Syzygy in 10 days

After 10 days on 16 August 2099 at 08:54 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
