Moderate tide

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 -953 /

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation -953 of Meeus index or from Brown series.

Current lunationNext

Synodic month length 0 days

Length of current -953 lunation is days, 1 hour and 1 minute. It is longer than next lunation -953 length.

Lunation length same as the mean

Length of current synodic month is equal to the mean length of synodic month. It is 6 hours and 9 minutes longer than the 21st century shortest and 7 hours and 3 minutes shorter than the 21st century longest synodic month.

Lunar orbit position on

True anomaly ∠0°

This New Moon true anomaly is ∠0°. At beginning of next synodic month true anomaly will be ∠0°. 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 before perigee

19385 days after point of apogee on at : in &#; . The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on at : in &#; .

Next perigee

Distance to Moon 384 714 km

Moon is 384 714 km (239 050 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 0 km (0 mi).

Moon before descending node

Moon before northern standstill

19385 days after previous South standstill on at : in &#; , when Moon has reached southern declination of ∠°. Next day the lunar orbit moves northward to face North declination of ∠° in the next northern standstill on at : in &#; .

Next standstill

Syzygy in 1 day

After 1 day on at : in &#; , the Moon will be in geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
