Moon phase and lunation details
Moonrise and moonset
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon in ♐ Sagittarius
Moon is leaving the last ∠4° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.
Apparent angular diameter ∠1840"
Lunar disc appears visually 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1840" and ∠1908".
Harvest Moon after 7 days
Next Full Moon is the Harvest Moon of September 2010 after 7 days on 23 September 2010 at 09:17.
Upcoming main Moon phases
- Full Moon in Aries ♈ on 23 September 2010 at 09:17
- Last Quarter in Cancer ♋ on 1 October 2010 at 03:52
- New Moon in Libra ♎ on 7 October 2010 at 18:44
- First Quarter in Capricorn ♑ on 14 October 2010 at 21:27
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 132 / 1085
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.
Synodic month length 29.34 days
The length of the lunation is 29 days, 8 hours and 15 minutes. It is 1 hour and 52 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
Lunation length shorter than mean
The length of the current synodic month is 4 hours and 29 minutes shorter than the mean synodic month length. It is 1 hour and 40 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠4.6°
At the beginning of the lunation cycle the true anomaly is ∠4.6°. At the beginning of next synodic month the true anomaly is going to be ∠20.4°.
Moon before perigee
7 days after point of perigee on 8 September 2010 at 04:00 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 21 September 2010 at 08:03 in ♓ Pisces.
Distance to Moon 389 493 km
The Moon is 389 493 km (242 020 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 169 km (252 382 mi).
Moon before ascending node
11 days after descending node on 4 September 2010 at 00:16 in ♋ Cancer. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 16 September 2010 at 13:56 in ♑ Capricorn.
Draconic month
25 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the second to the final part of the cycle.
Moon after southern standstill
1 day since the previous standstill on 14 September 2010 at 23:47 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.710°, the lunar orbit is extending northward over the next 14 days to face maximum declination of ∠24.555° at the point of next northern standstill on 29 September 2010 at 17:37 in ♊ Gemini.
Syzygy in 7 days
In 7 days on 23 September 2010 at 09:17 in ♈ Aries the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
