Previous main lunar phase is the Full Moon before 4 days on 9 August 2025 at 07:55.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing about ∠15° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1959" and ∠1894".
Next Full Moon is the Harvest Moon of September 2025 after 25 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 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 316 of Meeus index or 1269 from Brown series.
Length of current 316 lunation is 29 days, 10 hours and 55 minutes. It is 2 hours and 53 minutes shorter than next lunation 317 length.
Length of current synodic month is 1 hour and 49 minutes shorter than the mean length of synodic month, but it is still 4 hours and 20 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠60.5°. At beginning of next synodic month true anomaly will be ∠93°. 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°).
11 days after point of apogee on 1 August 2025 at 20:37 in ♏ Scorpio. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 14 August 2025 at 18:01 in ♈ Aries.
Moon is 365 973 km (227 405 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 369 287 km (229 464 mi).
1 day after its ascending node on 11 August 2025 at 14:53 in ♓ Pisces, 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 24 August 2025 at 15:41 in ♍ Virgo.
1 day after beginning of current draconic month in ♓ Pisces, the Moon is moving from the beginning to the first part of it.
7 days after previous South standstill on 5 August 2025 at 13:37 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.534°. Next 5 days the lunar orbit moves northward to face North declination of ∠28.585° in the next northern standstill on 18 August 2025 at 15:59 in ♊ Gemini.
After 9 days on 23 August 2025 at 06:06 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
