First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 45% and growing larger. The 7 days young Moon is in ♈ Aries.
* The exact date and time of this First Quarter phase is on 24 January 2018 at 22:20 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 2.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1949".
Next Full Moon is the Wolf Moon of January 2018 after 7 days on 31 January 2018 at 13:27.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 7 days young. Earth's natural satellite is moving through the first 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°).
9 days after point of apogee on 15 January 2018 at 02:10 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 30 January 2018 at 09:54 in ♋ Cancer.
Moon is 375 918 km (233 585 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 995 km (223 069 mi).
5 days after its descending node on 18 January 2018 at 14:28 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 31 January 2018 at 18:46 in ♌ Leo.
20 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the second to the final part of it.
8 days after previous South standstill on 15 January 2018 at 16:28 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.048°. Next 4 days the lunar orbit moves northward to face North declination of ∠20.027° in the next northern standstill on 29 January 2018 at 11:32 in ♋ Cancer.
After 7 days on 31 January 2018 at 13:27 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
