First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 61% and growing larger. The 8 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 ∠20° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 7.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1901".
Next Full Moon is the Harvest Moon of September 2017 after 6 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 8 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.
Length of current 218 lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 minutes shorter than next lunation 219 length.
Length of current synodic month is 1 hour and 44 minutes shorter than the mean length of synodic month, but it is still 4 hours and 25 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠49.5°. At beginning of next synodic month true anomaly will be ∠79°. 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°).
Moon is reaching point of apogee on this date at 11:25, this is 11 days after last perigee on 18 August 2017 at 13:14 in ♋ Cancer. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 14 days ahead, until it will get to the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.
This apogee Moon is 404 307 km (251 225 mi) away from Earth. This is the year's closest apogee of 2017. It is 1 101 km farther than the mean apogee distance, but it is still 256 km closer than the farthest apogee of 21st century.
9 days after its ascending node on 21 August 2017 at 10:34 in ♌ Leo, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.
9 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
12 days after previous North standstill on 18 August 2017 at 06:50 in ♋ Cancer, when Moon has reached northern declination of ∠19.381°. Next day the lunar orbit moves southward to face South declination of ∠-19.393° in the next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
After 6 days on 6 September 2017 at 07:03 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
