The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 224 of Meeus index or 1177 from Brown series.

Synodic month length 29.67 days

Length of current 224 lunation is 29 days, 16 hours and 6 minutes. It is 3 hours and 20 minutes longer than next lunation 225 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 22 minutes longer than the mean length of synodic month, but it is still 3 hours and 41 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠227.1°

This lunation true anomaly is ∠227.1°. At the beginning of next synodic month true anomaly will be ∠262.6°. 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

12 days after point of apogee on 11 February 2018 at 14:16 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 27 February 2018 at 14:48 in ♋ Cancer.

Distance to Moon 364 522 km

Moon is 364 522 km (226 503 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 363 938 km (226 141 mi).

Moon before ascending node

9 days after its descending node on 14 February 2018 at 21:11 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 28 February 2018 at 05:03 in ♌ Leo.

Moon before northern standstill

12 days after previous South standstill on 11 February 2018 at 23:21 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.026°. Next day the lunar orbit moves northward to face North declination of ∠20.056° in the next northern standstill on 25 February 2018 at 20:07 in ♋ Cancer.

Syzygy in 5 days

After 5 days on 2 March 2018 at 00:51 in ♍ Virgo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
