Main moon phases of the following lunar cycle.
Moon is passing about ∠7° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2025 after 14 days on 7 October 2025 at 03:47.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1794" and ∠1912".
At 19:54 on this date the Moon completes the old and enters a new synodic month with lunation 318 of Meeus index or lunation 1271 from Brown series.
The length of the lunation is 29 days, 16 hours and 31 minutes. It is 1 hour and 51 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 3 hours and 47 minutes longer than the mean synodic month length. It is 3 hours and 16 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit is ∠127.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠156.8°.
11 days since point of perigee on 10 September 2025 at 12:09 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 26 September 2025 at 09:46 in ♏ Scorpio.
The Moon is 399 471 km (248 220 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 552 km (251 998 mi).
1 day after descending node on 20 September 2025 at 23:13 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 5 October 2025 at 09:20 in ♓ Pisces.
7 days since the last northern standstill on 14 September 2025 at 21:23 in ♊ Gemini when the Moon has reached North declination of ∠28.630° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.599° at the point of next southern standstill on 29 September 2025 at 06:09 in ♐ Sagittarius.
14 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
