Moon phase and lunation details
2 days after Full Moon
Previous main lunar phase is the Full Moon before 2 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 in ♈ Aries
Moon is passing about ∠16° of ♈ Aries tropical zodiac sector.
Apparent angular diameter ∠1796"
Lunar disc appears visually 5.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1903".
Sturgeon Moon before 2 days
Next Full Moon is the Harvest Moon of September 2012 after 26 days on 30 September 2012 at 03:19.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 8 September 2012 at 13:15
- New Moon in Virgo ♍ on 16 September 2012 at 02:11
- First Quarter in Sagittarius ♐ on 22 September 2012 at 19:41
- Full Moon in Aries ♈ on 30 September 2012 at 03:19
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 17 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.
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 before apogee
10 days after point of perigee on 23 August 2012 at 19:39 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 7 September 2012 at 06:00 in ♊ Gemini.
Distance to Moon 399 206 km
Moon is 399 206 km (248 055 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 404 296 km (251 218 mi).
Moon before descending node
10 days after its ascending node on 24 August 2012 at 11:38 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 7 September 2012 at 02:08 in ♉ Taurus.
Draconic month
10 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
8 days after previous South standstill on 25 August 2012 at 18:40 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.379°. Next 5 days 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 12 days
After 12 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.
