First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 62% and growing larger. The 8 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 27 July 2031 at 10:35 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠19° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 1.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1924" and ∠1890".
Next Full Moon is the Sturgeon Moon of August 2031 after 5 days on 3 August 2031 at 01:45.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.
Length of current 390 lunation is 29 days, 14 hours and 52 minutes. It is 37 minutes longer than next lunation 391 length.
Length of current synodic month is 2 hours and 8 minutes longer than the mean length of synodic month, but it is still 4 hours and 55 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠188.7°. At the beginning of next synodic month true anomaly will be ∠213.5°. 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°).
9 days after point of apogee on 18 July 2031 at 14:28 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 2 August 2031 at 06:47 in ♑ Capricorn.
Moon is 372 623 km (231 537 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 358 060 km (222 488 mi).
Moon is in ascending node in ♏ Scorpio at 23:54 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 10 August 2031 at 14:10 in ♉ Taurus.
At 23:54 on this date the Moon is completing its previous draconic month and is entering the new one.
12 days after previous North standstill on 16 July 2031 at 09:01 in ♊ Gemini, when Moon has reached northern declination of ∠21.045°. Next 2 days the lunar orbit moves southward to face South declination of ∠-20.951° in the next southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius.
After 5 days on 3 August 2031 at 01:45 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
