Moon phase and lunation details
3 days after Full Moon
Previous main lunar phase is the Full Moon before 3 days on 24 August 2010 at 17:05.
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 ∠17° of ♈ Aries tropical zodiac sector.
Apparent angular diameter ∠1791"
Lunar disc appears visually 5.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1791" and ∠1900".
Sturgeon Moon before 3 days
Next Full Moon is the Harvest Moon of September 2010 after 25 days on 23 September 2010 at 09:17.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 1 September 2010 at 17:22
- New Moon in Virgo ♍ on 8 September 2010 at 10:30
- First Quarter in Sagittarius ♐ on 15 September 2010 at 05:50
- Full Moon in Aries ♈ on 23 September 2010 at 09:17
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 131 / 1084
The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.
Synodic month length 29.31 days
Length of current 131 lunation is 29 days, 7 hours and 22 minutes. This is the year's shortest synodic month of 2010. It is 53 minutes shorter than next lunation 132 length.
Lunation length shorter than mean
Length of current synodic month is 5 hours and 22 minutes shorter than the mean length of synodic month, but it is still 47 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠349.5°
This New Moon true anomaly is ∠349.5°. At beginning of next synodic month true anomaly will be ∠4.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon after apogee
3 days after point of apogee on 25 August 2010 at 05:51 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 8 September 2010 at 04:00 in ♍ Virgo.
Distance to Moon 400 298 km
Moon is 400 298 km (248 734 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 357 193 km (221 949 mi).
Moon before descending node
7 days after its ascending node on 20 August 2010 at 12:13 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.
Draconic month
7 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
Moon before northern standstill
9 days after previous South standstill on 18 August 2010 at 17:07 in ♐ Sagittarius, when Moon has reached southern declination of ∠-24.929°. Next 4 days the lunar orbit moves northward to face North declination of ∠24.807° in the next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.
Syzygy in 10 days
After 10 days on 8 September 2010 at 10:30 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
