First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 52% and growing larger. The 7 days young Moon is in ♒ Aquarius.
* The exact date and time of this First Quarter phase is on 23 October 2031 at 07:36 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠2° of ♒ Aquarius tropical zodiac sector.
Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1929".
Next Full Moon is the Hunter Moon of October 2031 after 6 days on 30 October 2031 at 07:33.
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 393 of Meeus index or 1346 from Brown series.
Length of current 393 lunation is 29 days, 12 hours and 49 minutes. It is 53 minutes longer than next lunation 394 length.
Length of current synodic month is 5 minutes longer than the mean length of synodic month, but it is still 6 hours and 58 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠281.8°. At the beginning of next synodic month true anomaly will be ∠312.6°. 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°).
1 day after point of perigee on 22 October 2031 at 20:06 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 6 November 2031 at 02:45 in ♌ Leo.
Moon is 363 372 km (225 789 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 522 km (251 358 mi).
5 days after its ascending node on 18 October 2031 at 06:54 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 31 October 2031 at 06:09 in ♉ Taurus.
5 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
3 days after previous South standstill on 20 October 2031 at 11:06 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.359°. Next 10 days the lunar orbit moves northward to face North declination of ∠20.333° in the next northern standstill on 2 November 2031 at 15:55 in ♊ Gemini.
After 6 days on 30 October 2031 at 07:33 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
