Quarter ♏ Scorpio
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♎ Libra.
* The exact date and time of this First Quarter phase is on 17 July 2040 at 09:16 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1878" and ∠1888".
Next Full Moon is the Buck Moon of July 2040 after 6 days on 24 July 2040 at 02:05.
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 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 501 of Meeus index or 1454 from Brown series.
Length of current 501 lunation is 29 days, 15 hours and 12 minutes. This is the year's longest synodic month of 2040. It is 25 minutes longer than next lunation 502 length.
Length of current synodic month is 2 hours and 28 minutes longer than the mean length of synodic month, but it is still 4 hours and 35 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠175.9°. At the beginning of next synodic month true anomaly will be ∠199°. 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°).
7 days after point of apogee on 9 July 2040 at 20:13 in ♋ Cancer. 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 23 July 2040 at 19:15 in ♑ Capricorn.
Moon is 381 765 km (237 218 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 357 113 km (221 900 mi).
11 days after its ascending node on 5 July 2040 at 15:32 in ♉ Taurus, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 20 July 2040 at 02:18 in ♐ Sagittarius.
11 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the beginning to the first part of it.
8 days after previous North standstill on 8 July 2040 at 16:14 in ♋ Cancer, when Moon has reached northern declination of ∠26.142°. Next 5 days the lunar orbit moves southward to face South declination of ∠-26.179° in the next southern standstill on 22 July 2040 at 14:28 in ♑ Capricorn.
After 6 days on 24 July 2040 at 02:05 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
