Neap tide
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunation 222 / 1175
The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 222 of Meeus index or 1175 from Brown series.
Synodic month length 29.82 days
Length of current 222 lunation is 29 days, 19 hours and 47 minutes. This is the year's longest synodic month of 2018. It is 59 minutes longer than next lunation 223 length.
Lunation length longer than mean
Length of current synodic month is 7 hours and 3 minutes longer than the mean length of synodic month and it is the longest synodic month length of a for 21st century.
Lunar orbit position on
True anomaly ∠173.3°
This lunation true anomaly is ∠173.3°. At the beginning of next synodic month true anomaly will be ∠198.1°. 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 apogee
7 days after point of perigee on 1 January 2018 at 21:54 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 15 January 2018 at 02:10 in ♑ Capricorn.
Distance to Moon 390 257 km
Moon is 390 257 km (242 494 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 406 461 km (252 563 mi).
Moon after ascending node
5 days after its ascending node on 4 January 2018 at 07:48 in ♌ Leo, the Moon is following the northern part of its orbit for the next 9 days, until it will cross the ecliptic from North to South in descending node on 18 January 2018 at 14:28 in ♒ Aquarius.
Draconic month
5 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
Moon before southern standstill
7 days after previous North standstill on 2 January 2018 at 00:01 in ♋ Cancer, when Moon has reached northern declination of ∠20.055°. Next 6 days the lunar orbit moves southward to face South declination of ∠-20.048° in the next southern standstill on 15 January 2018 at 16:28 in ♑ Capricorn.
Syzygy in 7 days
After 7 days on 17 January 2018 at 02:17 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
