Synodic month length 29.53 days

Length of current 289 lunation is 29 days, 12 hours and 44 minutes. It is 1 hour and 11 minutes shorter than next lunation 290 length.

Lunation length same as the mean

Length of current synodic month is equal to the mean length of synodic month. It is 6 hours and 9 minutes longer than the 21st century shortest and 7 hours and 3 minutes shorter than the 21st century longest synodic month.

Lunar orbit position on

True anomaly ∠92.6°

This New Moon true anomaly is ∠92.6°. At beginning of next synodic month true anomaly will be ∠127.4°. 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 apogee

5 days after point of apogee on 26 May 2023 at 01:39 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 6 June 2023 at 23:07 in ♑ Capricorn.

Distance to Moon 391 319 km

Moon is 391 319 km (243 154 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 364 860 km (226 713 mi).

Moon before descending node

13 days after its ascending node on 17 May 2023 at 19:36 in ♈ Aries, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 1 June 2023 at 06:23 in ♏ Scorpio.

Moon before southern standstill

8 days after previous North standstill on 22 May 2023 at 14:08 in ♊ Gemini, when Moon has reached northern declination of ∠27.903°. Next 5 days the lunar orbit moves southward to face South declination of ∠-27.866° in the next southern standstill on 5 June 2023 at 16:21 in ♐ Sagittarius.

Syzygy in 3 days

After 3 days on 4 June 2023 at 03:42 in ♐ Sagittarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
