There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 1245 / 2198

The Moon is 14 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 1245 of Meeus index or 2198 from Brown series.

Synodic month length 29.38 days

Length of current 1245 lunation is 29 days, 9 hours and 13 minutes. It is 1 minute longer than next lunation 1246 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 31 minutes shorter than the mean length of synodic month, but it is still 2 hours and 38 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠320.8°

This lunation true anomaly is ∠320.8°. At the beginning of next synodic month true anomaly will be ∠340.4°. 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 before apogee

10 days after point of perigee on 6 September 2100 at 19:23 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 22 September 2100 at 16:20 in ♉ Taurus.

Previous perigeeNext apogee

Distance to Moon 395 089 km

Moon is 395 089 km (245 497 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 405 610 km (252 034 mi).

Moon in ascending node

New draconic month

At 01:56 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon after southern standstill

5 days after previous South standstill on 11 September 2100 at 14:42 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.345°. Next 8 days the lunar orbit moves northward to face North declination of ∠28.300° in the next northern standstill on 26 September 2100 at 01:39 in ♊ Gemini.

Syzygy in 1 day

After 1 day on 18 September 2100 at 11:32 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
