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 223 / 1176
The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 223 of Meeus index or 1176 from Brown series.
Synodic month length 29.78 days
Length of current 223 lunation is 29 days, 18 hours and 48 minutes. This is the year's longest synodic month of 2018. It is 2 hours and 42 minutes longer than next lunation 224 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, but it is still 59 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠198.1°
This lunation true anomaly is ∠198.1°. At the beginning of next synodic month true anomaly will be ∠227.1°. 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 after perigee
6 days after point of perigee on 30 January 2018 at 09:54 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 11 February 2018 at 14:16 in ♐ Sagittarius.
Distance to Moon 387 291 km
Moon is 387 291 km (240 651 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 405 701 km (252 091 mi).
Moon after ascending node
4 days after its ascending node on 31 January 2018 at 18:46 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 14 February 2018 at 21:11 in ♒ Aquarius.
Draconic month
4 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 29 January 2018 at 11:32 in ♋ Cancer, when Moon has reached northern declination of ∠20.027°. Next 6 days the lunar orbit moves southward to face South declination of ∠-20.026° in the next southern standstill on 11 February 2018 at 23:21 in ♑ Capricorn.
Syzygy in 10 days
After 10 days on 15 February 2018 at 21:05 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
