Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 45% and getting smaller. The 22 days old Moon is in ♉ Taurus.
* The exact date and time of this Last Quarter phase is on 15 August 2017 at 01:15 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1895".
Next Full Moon is the Harvest Moon of September 2017 after 21 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 22 days old. Earth's natural satellite is moving through the last 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°).
12 days after point of apogee on 2 August 2017 at 17:55 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.
Moon is 364 581 km (226 540 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 366 129 km (227 502 mi).
7 days after its descending node on 8 August 2017 at 10:56 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 21 August 2017 at 10:34 in ♌ Leo.
21 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the second to the final part of it.
10 days after previous South standstill on 4 August 2017 at 18:17 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 2 days the lunar orbit moves northward to face North declination of ∠19.381° in the next northern standstill on 18 August 2017 at 06:50 in ♋ Cancer.
After 6 days on 21 August 2017 at 18:30 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
