Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 56% and getting smaller. The 21 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 22 September 2019 at 02:41 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠21° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1911".
Next Full Moon is the Hunter Moon of October 2019 after 22 days on 13 October 2019 at 21:08.
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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 243 of Meeus index or 1196 from Brown series.
Length of current 243 lunation is 29 days, 7 hours and 49 minutes. It is 1 hour and 23 minutes shorter than next lunation 244 length.
Length of current synodic month is 4 hours and 55 minutes shorter than the mean length of synodic month, but it is still 1 hour and 14 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠356.3°. At beginning of next synodic month true anomaly will be ∠11.4°. 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°).
7 days after point of apogee on 13 September 2019 at 13:32 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 28 September 2019 at 02:27 in ♍ Virgo.
Moon is 381 332 km (236 949 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 357 803 km (222 328 mi).
12 days after its descending node on 8 September 2019 at 17:35 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 23 September 2019 at 06:30 in ♋ Cancer.
25 days after beginning of current draconic month in ♋ Cancer, the Moon is moving from the second to the final part of it.
13 days after previous South standstill on 8 September 2019 at 09:39 in ♑ Capricorn, when Moon has reached southern declination of ∠-22.539°. Next day the lunar orbit moves northward to face North declination of ∠22.681° in the next northern standstill on 23 September 2019 at 01:54 in ♋ Cancer.
After 7 days on 28 September 2019 at 18:26 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
