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 in ♏ Scorpio

Moon is passing about ∠20° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1890".

Sturgeon Moon after 5 days

Next Full Moon is the Sturgeon Moon of August 2012 after 5 days on 2 August 2012 at 03:27.

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 155 / 1108

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 155 of Meeus index or 1108 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.48 days

Length of current 155 lunation is 29 days, 11 hours and 30 minutes. It is 1 hour and 14 minutes longer than next lunation 156 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 14 minutes shorter than the mean length of synodic month, but it is still 4 hours and 55 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠248.7°

This lunation true anomaly is ∠248.7°. At the beginning of next synodic month true anomaly will be ∠283.7°. 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 perigee

13 days after point of apogee on 13 July 2012 at 16:47 in ♉ Taurus. 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 29 July 2012 at 08:30 in ♐ Sagittarius.

Distance to Moon 363 360 km

Moon is 363 360 km (225 781 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 367 318 km (228 241 mi).

Moon before ascending node

12 days after its descending node on 14 July 2012 at 20:55 in ♉ Taurus, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 28 July 2012 at 10:34 in ♐ Sagittarius.

Draconic month

26 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.

Moon before southern standstill

11 days after previous North standstill on 16 July 2012 at 01:18 in ♊ Gemini, when Moon has reached northern declination of ∠21.665°. Next 2 days the lunar orbit moves southward to face South declination of ∠-21.592° in the next southern standstill on 29 July 2012 at 12:11 in ♐ Sagittarius.

Syzygy in 5 days

After 5 days on 2 August 2012 at 03:27 in ♒ Aquarius, the Moon will be in First Quarter geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
