Synodic month length 29.38 days

Length of current 1133 lunation is 29 days, 9 hours and 13 minutes. It is 19 minutes longer than next lunation 1134 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 31 minutes shorter than the mean length of synodic month, but it is still 2 hours and 38 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠310.2°

This lunation true anomaly is ∠310.2°. At the beginning of next synodic month true anomaly will be ∠332.3°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after apogee

3 days after point of apogee on 3 September 2091 at 01:49 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 15 September 2091 at 01:40 in ♎ Libra.

Moon before ascending node

8 days after its descending node on 28 August 2091 at 18:22 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 12 September 2091 at 03:32 in ♍ Virgo.

Moon before northern standstill

13 days after previous South standstill on 24 August 2091 at 11:30 in ♑ Capricorn, when Moon has reached southern declination of ∠-18.873°. Next day the lunar orbit moves northward to face North declination of ∠18.885° in the next northern standstill on 8 September 2091 at 00:27 in ♋ Cancer.

Syzygy in 6 days

After 6 days on 13 September 2091 at 09:34 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
