Gibbous ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 58% and growing larger. The 8 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 25 August 2031 at 18:40 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠12° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 2.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1951" and ∠1899".
Next Full Moon is the Harvest Moon of September 2031 after 5 days on 1 September 2031 at 09:20.
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 391 of Meeus index or 1344 from Brown series.
Length of current 391 lunation is 29 days, 14 hours and 15 minutes. It is 41 minutes longer than next lunation 392 length.
Length of current synodic month is 1 hour and 31 minutes longer than the mean length of synodic month, but it is still 5 hours and 32 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠213.5°. At the beginning of next synodic month true anomaly will be ∠245.2°. 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°).
11 days after point of apogee on 14 August 2031 at 21:37 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 30 August 2031 at 12:53 in ♒ Aquarius.
Moon is 367 345 km (228 258 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 361 684 km (224 740 mi).
1 day after its ascending node on 25 August 2031 at 01:21 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 6 September 2031 at 16:34 in ♉ Taurus.
1 day after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
At 23:55 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-20.731°. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠20.623° in its northern standstill point on 8 September 2031 at 23:27 in ♊ Gemini.
After 5 days on 1 September 2031 at 09:20 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
