Quarter ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 29 August 2017 at 08:13 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1900".
Next Full Moon is the Harvest Moon of September 2017 after 7 days on 6 September 2017 at 07:03.
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 218 of Meeus index or 1171 from Brown series.
The length of the lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 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 1 hour and 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠49.5°. At the beginning of next synodic month the true anomaly is going to be ∠79°.
10 days after point of perigee on 18 August 2017 at 13:14 in ♋ Cancer. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 30 August 2017 at 11:25 in ♐ Sagittarius.
The Moon is 404 863 km (251 570 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 307 km (251 225 mi).
8 days after ascending node on 21 August 2017 at 10:34 in ♌ Leo. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.
8 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the beginning to the first part of the cycle.
11 days since the previous standstill on 18 August 2017 at 06:50 in ♋ Cancer when the Moon has reached North declination of ∠19.381°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
In 7 days on 6 September 2017 at 07:03 in ♓ Pisces 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.
