Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 7 September 2025 at 18:09.

Moonrise and moonset

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.

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.

Lunation 317 / 1270

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 317 of Meeus index or 1270 from Brown series.

Synodic month length 29.58 days

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.

Lunation length longer than mean

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.

Lunar orbit position on

True anomaly ∠93°

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°).

Moon after perigee

2 days after point of perigee on 10 September 2025 at 12:09 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 26 September 2025 at 09:46 in ♏ Scorpio.

Distance to Moon 364 374 km

Moon is 364 374 km (226 412 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 405 552 km (251 998 mi).

Moon after ascending node

5 days after its ascending node on 7 September 2025 at 23:08 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 20 September 2025 at 23:13 in ♍ Virgo.

Moon before northern standstill

11 days after previous South standstill on 1 September 2025 at 22:04 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.623°. Next day the lunar orbit moves northward to face North declination of ∠28.630° in the next northern standstill on 14 September 2025 at 21:23 in ♊ Gemini.

Syzygy in 8 days

After 8 days on 21 September 2025 at 19:54 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
