Next Full Moon is the Sturgeon Moon of August 2007 after 7 days on 28 August 2007 at 10:35.

Upcoming main Moon phases

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.

Synodic month length 29.57 days

Length of current 94 lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 34 minutes shorter than next lunation 95 length.

Lunation length longer than mean

Length of current synodic month is 58 minutes longer than the mean length of synodic month, but it is still 6 hours and 5 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠97.3°

This New Moon true anomaly is ∠97.3°. At beginning of next synodic month true anomaly will be ∠131.4°. 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 apogee

1 day after point of apogee on 19 August 2007 at 03:28 in ♏ Scorpio. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 31 August 2007 at 00:12 in ♈ Aries.

Distance to Moon 404 374 km

Moon is 404 374 km (251 266 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 364 174 km (226 287 mi).

Moon after descending node

6 days after its descending node on 14 August 2007 at 07:25 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 28 August 2007 at 14:27 in ♒ Aquarius.

Moon before southern standstill

11 days after previous North standstill on 8 August 2007 at 23:02 in ♊ Gemini, when Moon has reached northern declination of ∠28.342°. Next 2 days the lunar orbit moves southward to face South declination of ∠-28.377° in the next southern standstill on 23 August 2007 at 08:02 in ♐ Sagittarius.

Syzygy in 7 days

After 7 days on 28 August 2007 at 10:35 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
