First Quarter on . The illuminated surface of the moon is 50% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 16 January 2073 at 11:33 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 leaving the last ∠3° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Next Full Moon is the Wolf Moon of January 2073 after 7 days on 23 January 2073 at 20:05.
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 9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1950".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 903 of Meeus index or 1856 from Brown series.
The length of this lunation is 29 days, 17 hours and 30 minutes and it is 1 hour and 5 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 4 hours and 46 minutes longer than the mean synodic month length. It is 2 hours and 17 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 ∠105.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠140.9°.
2 days since point of apogee on 14 January 2073 at 02:24 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 25 January 2073 at 21:07 in ♌ Leo.
The Moon is 402 051 km (249 823 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 362 567 km (225 289 mi).
4 days after descending node on 11 January 2073 at 18:17 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 January 2073 at 14:53 in ♌ Leo.
9 days since the last southern standstill on 7 January 2073 at 10:43 in ♑ Capricorn when the Moon has reached South declination of ∠-19.079° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠19.043° at the point of next northern standstill on 21 January 2073 at 22:36 in ♋ Cancer.
18 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 23 January 2073 at 20:05 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.
