* The exact date and time of this Last Quarter phase is on 4 October 2015 at 21:06 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠6° of ♋ Cancer tropical zodiac sector.
Lunar disc appears visually 2.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1867" and ∠1918".
Next Full Moon is the Hunter Moon of October 2015 after 23 days on 27 October 2015 at 12:05.
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 194 of Meeus index or 1147 from Brown series.
Length of current 194 lunation is 29 days, 17 hours and 24 minutes. It is 17 minutes shorter than next lunation 195 length.
Length of current synodic month is 4 hours and 40 minutes longer than the mean length of synodic month, but it is still 2 hours and 23 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠169.3°. At the beginning of next synodic month true anomaly will be ∠192.9°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
6 days after point of perigee on 28 September 2015 at 01:46 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 11 October 2015 at 13:17 in ♍ Virgo.
Moon is 383 987 km (238 598 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 406 389 km (252 518 mi).
6 days after its descending node on 27 September 2015 at 21:04 in ♓ Pisces, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 11 October 2015 at 10:54 in ♎ Libra.
20 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the second to the final part of it.
1 day after previous North standstill on 3 October 2015 at 23:55 in ♊ Gemini, when Moon has reached northern declination of ∠18.140°. Next 14 days the lunar orbit moves southward to face South declination of ∠-18.190° in the next southern standstill on 18 October 2015 at 18:31 in ♐ Sagittarius.
After 8 days on 13 October 2015 at 00:06 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
