First Quarter on . The illuminated surface of the moon is 51% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 9 January 2071 at 11:08 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠20° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2071 after 6 days on 16 January 2071 at 02:35.
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.
Lunar disc appears visually 2.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1900" and ∠1951".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 878 of Meeus index or 1831 from Brown series.
The length of this lunation is 29 days, 19 hours and 1 minute and it is 1 hour and 44 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2071. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 6 hours and 16 minutes longer than the mean synodic month length. It is 47 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠187.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠214.7°.
8 days since point of apogee on 31 December 2070 at 14:10 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 15 January 2071 at 08:40 in ♋ Cancer.
The Moon is 377 256 km (234 416 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 535 km (222 162 mi).
1 day after descending node on 8 January 2071 at 19:49 in ♈ Aries the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 January 2071 at 06:04 in ♎ Libra.
9 days since the last southern standstill on 31 December 2070 at 07:48 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.553° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.487° at the point of next northern standstill on 14 January 2071 at 05:41 in ♊ Gemini.
15 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 16 January 2071 at 02:35 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
