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 leaving the last ∠4° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1893".

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2012 after 21 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 22 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 in apogee

Moon is reaching point of apogee on this date at 10:51, this is 12 days after last perigee on 29 July 2012 at 08:30 in ♐ Sagittarius. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 13 days ahead, until it will get to the point of next perigee on 23 August 2012 at 19:39 in ♏ Scorpio.

Distance to Moon 404 125 km

This apogee Moon is 404 125 km (251 112 mi) away from Earth. This is the year's closest apogee of 2012. It is 1 283 km farther than the mean apogee distance, but it is still 74 km closer than the farthest apogee of 21st century.

Moon before descending node

13 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

13 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

11 days after previous South standstill on 29 July 2012 at 12:11 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.592°. Next day 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 7 days

After 7 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.
