Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 31 August 2012 at 13:58.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon is entering ♊ Gemini

Moon is passing first ∠4° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1905".

Sturgeon Moon before 6 days

Next Full Moon is the Harvest Moon of September 2012 after 22 days on 30 September 2012 at 03:19.

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 156 / 1109

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 156 of Meeus index or 1109 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.43 days

Length of current 156 lunation is 29 days, 10 hours and 16 minutes. It is 24 minutes longer than next lunation 157 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 28 minutes shorter than the mean length of synodic month, but it is still 3 hours and 41 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠283.7°

This lunation true anomaly is ∠283.7°. At the beginning of next synodic month true anomaly will be ∠312.9°. 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 06:00, this is 14 days after last perigee on 23 August 2012 at 19:39 in ♏ Scorpio. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 11 days ahead, until it will get to the point of next perigee on 19 September 2012 at 02:52 in ♏ Scorpio.

Previous perigeeNext perigee

Distance to Moon 404 296 km

This apogee Moon is 404 296 km (251 218 mi) away from Earth. It is 1 112 km farther than the mean apogee distance, but it is still 2 413 km closer than the farthest apogee of 21st century.

Moon in descending node

Moon is in descending node in ♉ Taurus at 02:08 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 20 September 2012 at 12:54 in ♏ Scorpio.

Draconic month

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

Moon before northern standstill

12 days after previous South standstill on 25 August 2012 at 18:40 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.379°. Next day the lunar orbit moves northward to face North declination of ∠21.244° in the next northern standstill on 8 September 2012 at 18:10 in ♊ Gemini.

Syzygy in 8 days

After 8 days on 16 September 2012 at 02:11 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
