Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♉ Taurus

Moon is passing about ∠14° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1770"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1893".

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2012 after 22 days on 31 August 2012 at 13:58.

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 21 days old. Earth's natural satellite is moving through the last 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 apogee

11 days after point of perigee on 29 July 2012 at 08:30 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 10 August 2012 at 10:51 in ♉ Taurus.

Distance to Moon 404 996 km

Moon is 404 996 km (251 653 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 125 km (251 112 mi).

Moon before descending node

12 days after its ascending node on 28 July 2012 at 10:34 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 11 August 2012 at 00:04 in ♊ Gemini.

Draconic month

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

Moon before northern standstill

10 days after previous South standstill on 29 July 2012 at 12:11 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.592°. Next 2 days the lunar orbit moves northward to face North declination of ∠21.492° in the next northern standstill on 12 August 2012 at 09:47 in ♊ Gemini.

Syzygy in 8 days

After 8 days on 17 August 2012 at 15:54 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
