Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon is passing about ∠9° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1912".
The Full Moon this days is the Harvest of September 2040.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
The Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 503 of Meeus index or 1456 from Brown series.
Length of current 503 lunation is 29 days, 14 hours and 12 minutes. It is 42 minutes longer than next lunation 504 length.
Length of current synodic month is 1 hour and 28 minutes longer than the mean length of synodic month, but it is still 5 hours and 35 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠226.5°. At the beginning of next synodic month true anomaly will be ∠261.6°. 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°).
3 days after point of perigee on 18 September 2040 at 06:43 in ♒ Aquarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 30 September 2040 at 02:50 in ♋ Cancer.
Moon is 375 778 km (233 498 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 404 658 km (251 443 mi).
9 days after its descending node on 12 September 2040 at 06:11 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 24 September 2040 at 23:04 in ♉ Taurus.
23 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
6 days after previous South standstill on 15 September 2040 at 06:36 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.529°. Next 6 days the lunar orbit moves northward to face North declination of ∠26.630° in the next northern standstill on 28 September 2040 at 10:20 in ♋ Cancer.
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
