Synodic month length 29.74 days

Length of current 1224 lunation is 29 days, 17 hours and 43 minutes. It is 1 hour and 15 minutes shorter than next lunation 1225 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 59 minutes longer than the mean length of synodic month, but it is still 2 hours and 4 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠115.9°

This New Moon true anomaly is ∠115.9°. At beginning of next synodic month true anomaly will be ∠149°. 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

3 days after point of apogee on 27 December 2098 at 21:01 in ♒ Aquarius. 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 8 January 2099 at 18:21 in ♌ Leo.

Distance to Moon 398 273 km

Moon is 398 273 km (247 475 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 361 107 km (224 381 mi).

Moon after ascending node

1 day after its ascending node on 30 December 2098 at 20:34 in ♈ Aries, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 12 January 2099 at 15:35 in ♎ Libra.

Moon before northern standstill

8 days after previous South standstill on 22 December 2098 at 16:33 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.323°. Next 5 days the lunar orbit moves northward to face North declination of ∠28.354° in the next northern standstill on 6 January 2099 at 00:46 in ♋ Cancer.

Syzygy in 6 days

After 6 days on 7 January 2099 at 01:50 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
