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.
Length of current 217 lunation is 29 days, 8 hours and 45 minutes. It is 2 hours and 15 minutes shorter than next lunation 218 length.
Length of current synodic month is 3 hours and 59 minutes shorter than the mean length of synodic month, but it is still 2 hours and 10 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠27.9°. At beginning of next synodic month true anomaly will be ∠49.5°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
8 days after point of perigee on 21 July 2017 at 17:09 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 2 August 2017 at 17:55 in ♐ Sagittarius.
Moon is 399 479 km (248 225 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 405 026 km (251 671 mi).
5 days after its ascending node on 25 July 2017 at 00:46 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 8 August 2017 at 10:56 in ♒ Aquarius.
5 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.
8 days after previous North standstill on 21 July 2017 at 22:11 in ♋ Cancer, when Moon has reached northern declination of ∠19.413°. Next 5 days the lunar orbit moves southward to face South declination of ∠-19.393° in the next southern standstill on 4 August 2017 at 18:17 in ♑ Capricorn.
After 8 days on 7 August 2017 at 18:11 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
