Moon in ♒ Aquarius

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

Apparent angular diameter ∠1816"

Lunar disc appears visually 4.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1816" and ∠1894".

It is Sturgeon Moon

The Full Moon this days is the Sturgeon of August 2011.

Upcoming main Moon phases

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 29.35 days

Length of current 143 lunation is 29 days, 8 hours and 24 minutes. It is 19 minutes longer than next lunation 144 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 20 minutes shorter than the mean length of synodic month, but it is still 1 hour and 49 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠312.1°

This lunation true anomaly is ∠312.1°. At the beginning of next synodic month true anomaly will be ∠333.4°. 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 2 August 2011 at 20:59 in ♍ Virgo. 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 18 August 2011 at 16:23 in ♈ Aries.

Distance to Moon 394 631 km

Moon is 394 631 km (245 212 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 405 161 km (251 755 mi).

Moon after ascending node

4 days after its ascending node on 9 August 2011 at 06:35 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 23 August 2011 at 17:23 in ♊ Gemini.

Moon after southern standstill

4 days after previous South standstill on 8 August 2011 at 23:15 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.270°. Next 10 days the lunar orbit moves northward to face North declination of ∠23.149° in the next northern standstill on 23 August 2011 at 12:17 in ♊ Gemini.
