Synodic month length 29.58 days

Length of current 1013 lunation is 29 days, 13 hours and 52 minutes. It is 2 hours and 26 minutes shorter than next lunation 1014 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 8 minutes longer than the mean length of synodic month, but it is still 5 hours and 55 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠52.5°

This New Moon true anomaly is ∠52.5°. At beginning of next synodic month true anomaly will be ∠84.8°. 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 in apogee

Moon is reaching point of apogee on this date at 00:48, this is 11 days after last perigee on 27 November 2081 at 03:46 in ♎ Libra. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 22 December 2081 at 10:49 in ♍ Virgo.

Distance to Moon 404 288 km

This apogee Moon is 404 288 km (251 213 mi) away from Earth. It is 1 120 km farther than the mean apogee distance, but it is still 2 421 km closer than the farthest apogee of 21st century.

Moon after ascending node

1 day after its ascending node on 7 December 2081 at 17:00 in ♓ Pisces, 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 21 December 2081 at 12:04 in ♍ Virgo.

Moon before northern standstill

7 days after previous South standstill on 1 December 2081 at 21:51 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.151°. Next 6 days the lunar orbit moves northward to face North declination of ∠28.126° in the next northern standstill on 16 December 2081 at 08:03 in ♊ Gemini.

Syzygy in 6 days

After 6 days on 16 December 2081 at 04:31 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
