The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1004 of Meeus index or 1957 from Brown series.

Synodic month length 29.71 days

Length of current 1004 lunation is 29 days, 16 hours and 58 minutes. It is 3 hours and 4 minutes longer than next lunation 1005 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 14 minutes longer than the mean length of synodic month, but it is still 2 hours and 49 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠202.2°

This lunation true anomaly is ∠202.2°. At the beginning of next synodic month true anomaly will be ∠231.2°. 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 before perigee

10 days after point of apogee on 8 March 2081 at 06:10 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 23 March 2081 at 16:38 in ♍ Virgo.

Distance to Moon 372 396 km

Moon is 372 396 km (231 396 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 359 723 km (223 522 mi).

Moon before descending node

7 days after its ascending node on 10 March 2081 at 22:30 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 24 March 2081 at 07:17 in ♍ Virgo.

Moon in northern standstill

At 10:34 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠28.673°. This is the year's northernmost lunar standstill of 2081. Next 12 days the lunar orbit will move in opposite southward direction to face South declination of ∠-28.653° in its southern standstill point on 31 March 2081 at 02:35 in ♐ Sagittarius.

Syzygy in 6 days

After 6 days on 25 March 2081 at 00:29 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
