* The exact date and time of this First Quarter phase is on 16 October 2018 at 18:02 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 ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 8.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1925".
Next Full Moon is the Hunter Moon of October 2018 after 8 days on 24 October 2018 at 16:45.
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 232 of Meeus index or 1185 from Brown series.
Length of current 232 lunation is 29 days, 12 hours and 15 minutes. It is 3 hours and 3 minutes shorter than next lunation 233 length.
Length of current synodic month is 29 minutes shorter than the mean length of synodic month, but it is still 5 hours and 40 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠49.6°. At beginning of next synodic month true anomaly will be ∠79.7°. 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°).
10 days after point of perigee on 5 October 2018 at 22:29 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 17 October 2018 at 19:16 in ♑ Capricorn.
Moon is 404 458 km (251 319 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 227 km (251 175 mi).
12 days after its ascending node on 4 October 2018 at 03:10 in ♌ Leo, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 17 October 2018 at 12:03 in ♒ Aquarius.

1 day after previous South standstill on 15 October 2018 at 17:26 in ♑ Capricorn, when Moon has reached southern declination of ∠-21.154°. Next 13 days the lunar orbit moves northward to face North declination of ∠21.292° in the next northern standstill on 29 October 2018 at 18:34 in ♋ Cancer.
After 8 days on 24 October 2018 at 16:45 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
