Previous main lunar phase is the Full Moon before 3 days on 31 January 2018 at 13:27.
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 ∠8° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1875" and ∠1946".
Next Full Moon is the Worm Moon of March 2018 after 25 days on 2 March 2018 at 00:51.
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 19 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.
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.
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.
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°).
5 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 7 days, until it get to the point of next apogee on 11 February 2018 at 14:16 in ♐ Sagittarius.
Moon is 382 374 km (237 596 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 405 701 km (252 091 mi).
3 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 10 days, until it will cross the ecliptic from North to South in descending node on 14 February 2018 at 21:11 in ♒ Aquarius.
3 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
6 days after previous North standstill on 29 January 2018 at 11:32 in ♋ Cancer, when Moon has reached northern declination of ∠20.027°. Next 7 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.
After 11 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.
