Quarter ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 47% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 16 August 2010 at 18:14 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠20° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1897" and ∠1895".
Next Full Moon is the Sturgeon Moon of August 2010 after 8 days on 24 August 2010 at 17:05.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.
The length of the 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 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°).
The length of the current synodic month is 5 hours and 22 minutes shorter than the mean synodic month length. It is 47 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠349.5°. At the beginning of next synodic month the true anomaly is going to be ∠4.6°.
5 days after point of perigee on 10 August 2010 at 17:56 in ♌ Leo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 8 days, until the Moon reaches the point of next apogee on 25 August 2010 at 05:51 in ♓ Pisces.
The Moon is 377 749 km (234 722 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 390 km (252 519 mi).
8 days after descending node on 7 August 2010 at 17:24 in ♋ Cancer. The Moon is located south of the ecliptic over the following 4 days, until the lunar orbit crosses from South to North in ascending node on 20 August 2010 at 12:13 in ♑ Capricorn.
23 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the second to the final part of the cycle.
10 days since the previous standstill on 6 August 2010 at 02:49 in ♊ Gemini when the Moon has reached North declination of ∠24.984°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-24.929° at the point of next southern standstill on 18 August 2010 at 17:07 in ♐ Sagittarius.
In 8 days on 24 August 2010 at 17:05 in ♒ Aquarius 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.
