* The exact date and time of this First Quarter phase is on 31 December 2079 at 08:29 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠12° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1951".
Next Full Moon is the Wolf Moon of January 2080 after 6 days on 7 January 2080 at 01:45.
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 989 of Meeus index or 1942 from Brown series.
Length of current 989 lunation is 29 days, 19 hours and 24 minutes. This is the year's longest synodic month of 2079. It is 1 hour and 8 minutes longer than next lunation 990 length.
Length of current synodic month is 6 hours and 40 minutes longer than the mean length of synodic month, but it is still 23 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠174.6°. At the beginning of next synodic month true anomaly will be ∠199.5°. 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°).
7 days after point of apogee on 23 December 2079 at 21:45 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 6 January 2080 at 19:49 in ♋ Cancer.
Moon is 381 948 km (237 331 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 356 505 km (221 522 mi).
Moon is in ascending node in ♈ Aries at 23:44 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 12 days to meet descending node on 13 January 2080 at 09:00 in ♎ Libra.
At 23:44 on this date the Moon is completing its previous draconic month and is entering the new one.
8 days after previous South standstill on 23 December 2079 at 10:12 in ♑ Capricorn, when Moon has reached southern declination of ∠-28.189°. Next 5 days the lunar orbit moves northward to face North declination of ∠28.224° in the next northern standstill on 6 January 2080 at 04:42 in ♋ Cancer.
After 6 days on 7 January 2080 at 01:45 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
