Quarter ♏ Scorpio
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 49% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 30 July 2017 at 15:23 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠6° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 5.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1890".
Next Full Moon is the Sturgeon Moon of August 2017 after 8 days on 7 August 2017 at 18:11.
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 217 of Meeus index or 1170 from Brown series.
The length of the lunation is 29 days, 8 hours and 45 minutes. It is 2 hours and 15 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 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠27.9°. At the beginning of next synodic month the true anomaly is going to be ∠49.5°.
8 days after point of perigee on 21 July 2017 at 17:09 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next apogee on 2 August 2017 at 17:55 in ♐ Sagittarius.
The Moon is 399 479 km (248 225 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 026 km (251 671 mi).
5 days after ascending node on 25 July 2017 at 00:46 in ♍ Virgo. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 8 August 2017 at 10:56 in ♒ Aquarius.
5 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the beginning to the first part of the cycle.
8 days since the previous standstill on 21 July 2017 at 22:11 in ♋ Cancer when the Moon has reached North declination of ∠19.413°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 4 August 2017 at 18:17 in ♑ Capricorn.
In 8 days on 7 August 2017 at 18:11 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.
