* The exact date and time of this First Quarter phase is on 31 August 2025 at 06:25 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠11° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1901".
Next Full Moon is the Harvest Moon of September 2025 after 7 days on 7 September 2025 at 18:09.
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 317 of Meeus index or 1270 from Brown series.
Length of current 317 lunation is 29 days, 13 hours and 48 minutes. It is 2 hours and 43 minutes shorter than next lunation 318 length.
Length of current synodic month is 1 hour and 4 minutes longer than the mean length of synodic month, but it is still 5 hours and 59 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠93°. At beginning of next synodic month true anomaly will be ∠127.7°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
1 day after point of apogee on 29 August 2025 at 15:34 in ♏ Scorpio. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 10 September 2025 at 12:09 in ♈ Aries.
Moon is 403 553 km (250 756 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 364 781 km (226 664 mi).
6 days after its descending node on 24 August 2025 at 15:41 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 7 September 2025 at 23:08 in ♓ Pisces.
19 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
12 days after previous North standstill on 18 August 2025 at 15:59 in ♊ Gemini, when Moon has reached northern declination of ∠28.585°. Next day the lunar orbit moves southward to face South declination of ∠-28.623° in the next southern standstill on 1 September 2025 at 22:04 in ♐ Sagittarius.
After 7 days on 7 September 2025 at 18:09 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
