Moon phase and lunation details
3 days after Full Moon
Previous main lunar phase is the Full Moon before 3 days on 13 August 2011 at 18:58.
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 ∠6° of ♈ Aries tropical zodiac sector.
Apparent angular diameter ∠1769"
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1895".
Sturgeon Moon before 3 days
Next Full Moon is the Harvest Moon of September 2011 after 25 days on 12 September 2011 at 09:27.
Upcoming main Moon phases
- Last Quarter in Taurus ♉ on 21 August 2011 at 21:55
- New Moon in Virgo ♍ on 29 August 2011 at 03:04
- First Quarter in Sagittarius ♐ on 4 September 2011 at 17:39
- Full Moon in Pisces ♓ on 12 September 2011 at 09:27
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 143 / 1096
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 143 of Meeus index or 1096 from Brown series.
Synodic month length 29.35 days
Length of current 143 lunation is 29 days, 8 hours and 24 minutes. It is 19 minutes longer than next lunation 144 length.
Lunation length shorter than mean
Length of current synodic month is 4 hours and 20 minutes shorter than the mean length of synodic month, but it is still 1 hour and 49 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠312.1°
This lunation true anomaly is ∠312.1°. At the beginning of next synodic month true anomaly will be ∠333.4°. 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
14 days after point of perigee on 2 August 2011 at 20:59 in ♍ Virgo. 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 18 August 2011 at 16:23 in ♈ Aries.
Distance to Moon 405 098 km
Moon is 405 098 km (251 716 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 161 km (251 755 mi).
Moon before descending node
8 days after its ascending node on 9 August 2011 at 06:35 in ♐ Sagittarius, 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 23 August 2011 at 17:23 in ♊ Gemini.
Draconic month
8 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 8 August 2011 at 23:15 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.270°. Next 6 days the lunar orbit moves northward to face North declination of ∠23.149° in the next northern standstill on 23 August 2011 at 12:17 in ♊ Gemini.
Syzygy in 11 days
After 11 days on 29 August 2011 at 03:04 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
