Synodic month length 29.74 days

Length of current 1239 lunation is 29 days, 17 hours and 48 minutes. This is the year's longest synodic month of 2100. It is 1 hour and 11 minutes longer than next lunation 1240 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 4 minutes longer than the mean length of synodic month, but it is still 1 hour and 59 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠151.4°

This New Moon true anomaly is ∠151.4°. At beginning of next synodic month true anomaly will be ∠176.6°. 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

4 days after point of perigee on 26 March 2100 at 14:59 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 10 April 2100 at 01:45 in ♈ Aries.

6 days after its descending node on 24 March 2100 at 20:18 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 6 April 2100 at 22:10 in ♓ Pisces.

Moon in southern standstill

At 15:42 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.525°. Next 14 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.446° in its northern standstill point on 15 April 2100 at 08:21 in ♊ Gemini.
