Synodic month length 29.58 days

The length of the lunation is 29 days, 13 hours and 48 minutes. It is 2 hours and 43 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 4 minutes longer than the mean synodic month length. It is 5 hours and 59 minutes shorter compared to 21st century's longest synodic month length.

True anomaly ∠93°

At the beginning of the lunation cycle the true anomaly is ∠93°. At the beginning of next synodic month the true anomaly is going to be ∠127.7°.

Moon before apogee

9 days after point of apogee on 29 August 2025 at 15:34 in ♏ Scorpio. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 10 September 2025 at 12:09 in ♈ Aries.

Distance to Moon 370 761 km

The Moon is 370 761 km (230 380 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 364 781 km (226 664 mi).

Moon after ascending node

1 day after ascending node on 7 September 2025 at 23:08 in ♓ Pisces. The Moon is located north of the ecliptic over the following 12 days, until the lunar orbit crosses from North to South in descending node on 20 September 2025 at 23:13 in ♍ Virgo.

Moon before northern standstill

6 days since the previous standstill on 1 September 2025 at 22:04 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.623°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.630° at the point of next northern standstill on 14 September 2025 at 21:23 in ♊ Gemini.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
