Synodic month length 29.34 days

Length of current 230 lunation is 29 days, 8 hours and 4 minutes. It is 1 hour and 41 minutes shorter than next lunation 231 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 40 minutes shorter than the mean length of synodic month, but it is still 1 hour and 29 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠11.2°

This New Moon true anomaly is ∠11.2°. At beginning of next synodic month true anomaly will be ∠28°. 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 before perigee

11 days after point of apogee on 23 August 2018 at 11:23 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 8 September 2018 at 01:21 in ♌ Leo.

Distance to Moon 369 333 km

Moon is 369 333 km (229 493 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 361 355 km (224 536 mi).

Moon before ascending node

10 days after its descending node on 24 August 2018 at 04:51 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 6 September 2018 at 22:42 in ♋ Cancer.

Moon before northern standstill

12 days after previous South standstill on 22 August 2018 at 02:58 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.773°. Next day the lunar orbit moves northward to face North declination of ∠20.837° in the next northern standstill on 5 September 2018 at 06:56 in ♋ Cancer.

Syzygy in 6 days

After 6 days on 9 September 2018 at 18:01 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
