Previous main lunar phase is the Full Moon before 2 days on 2 January 2018 at 02:24.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing about ∠18° of ♌ Leo tropical zodiac sector.
Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1948" and ∠1951".
Next Full Moon is the Wolf Moon of January 2018 after 27 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 17 days old. Earth's natural satellite is moving from the middle to the last 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°).
2 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 10 days, until it get to the point of next apogee on 15 January 2018 at 02:10 in ♑ Capricorn.
Moon is 367 927 km (228 619 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 406 461 km (252 563 mi).
Moon is in ascending node in ♌ Leo at 07:48 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 14 days to meet descending node on 18 January 2018 at 14:28 in ♒ Aquarius.
At 07:48 on this date the Moon is completing its previous draconic month and is entering the new one.
2 days after previous North standstill on 2 January 2018 at 00:01 in ♋ Cancer, when Moon has reached northern declination of ∠20.055°. Next 11 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 12 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.
