Moon is passing about ∠17° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1961"

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Synodic month length 29.62 days

The length of the lunation is 29 days, 14 hours and 52 minutes. It is 37 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 2 hours and 8 minutes longer than the mean synodic month length. It is 4 hours and 55 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠188.7°

At the beginning of the lunation cycle the true anomaly is ∠188.7°. At the beginning of next synodic month the true anomaly is going to be ∠213.5°.

Moon after perigee

1 day after point of perigee on 2 August 2031 at 06:47 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next apogee on 14 August 2031 at 21:37 in ♋ Cancer.

Distance to Moon 365 581 km

The Moon is 365 581 km (227 162 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 946 km (252 243 mi).

Moon after ascending node

5 days after ascending node on 28 July 2031 at 23:54 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 10 August 2031 at 14:10 in ♉ Taurus.

Moon after southern standstill

3 days since the previous standstill on 30 July 2031 at 15:45 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.951°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠20.868° at the point of next northern standstill on 12 August 2031 at 15:58 in ♊ Gemini.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
