Previous main lunar phase is the Last Quarter before 4 days on 8 January 2018 at 22:25.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Moon is passing about ∠14° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1951".
Next Full Moon is the Wolf Moon of January 2018 after 18 days on 31 January 2018 at 13:27.
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.
The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 222 of Meeus index or 1175 from Brown series.
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.
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.
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°).
11 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 day, until it get to the point of next apogee on 15 January 2018 at 02:10 in ♑ Capricorn.
Moon is 403 751 km (250 879 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 406 461 km (252 563 mi).
9 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 5 days, until it will cross the ecliptic from North to South in descending node on 18 January 2018 at 14:28 in ♒ Aquarius.
9 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
11 days after previous North standstill on 2 January 2018 at 00:01 in ♋ Cancer, when Moon has reached northern declination of ∠20.055°. Next 2 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.
After 3 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.
