Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is passing about ∠10° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1909"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1909" and ∠1888".

Buck Moon after 6 days

Next Full Moon is the Buck Moon of July 2010 after 6 days on 26 July 2010 at 01:37.

Upcoming main Moon phases

Neap tide

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.

Lunation 130 / 1083

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 130 of Meeus index or 1083 from Brown series.

Synodic month length 29.31 days

Length of current 130 lunation is 29 days, 7 hours and 28 minutes. It is 6 minutes longer than next lunation 131 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 16 minutes shorter than the mean length of synodic month, but it is still 53 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠332.7°

This lunation true anomaly is ∠332.7°. At the beginning of next synodic month true anomaly will be ∠349.5°. 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 after perigee

6 days after point of perigee on 13 July 2010 at 11:21 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 28 July 2010 at 23:50 in ♓ Pisces.

Distance to Moon 375 505 km

Moon is 375 505 km (233 328 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 405 955 km (252 249 mi).

Moon before ascending node

8 days after its descending node on 11 July 2010 at 07:30 in ♋ Cancer, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 24 July 2010 at 07:59 in ♑ Capricorn.

Moon before southern standstill

9 days after previous North standstill on 9 July 2010 at 16:50 in ♊ Gemini, when Moon has reached northern declination of ∠25.043°. Next 2 days the lunar orbit moves southward to face South declination of ∠-25.034° in the next southern standstill on 22 July 2010 at 11:12 in ♐ Sagittarius.

Syzygy in 6 days

After 6 days on 26 July 2010 at 01:37 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
