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 18 January 2043 at 09:05 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 first ∠0° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2043 after 6 days on 25 January 2043 at 06:56.
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 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1950".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 532 of Meeus index or 1485 from Brown series.
The length of this lunation is 29 days, 14 hours and 14 minutes and it is 2 hours and 12 minutes longer than the upcoming lunation's length. 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 1 hour and 30 minutes longer than the mean synodic month length. It is 5 hours and 33 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 ∠269.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠303°.
13 days since point of apogee on 4 January 2043 at 19:56 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 19 January 2043 at 20:02 in ♉ Taurus.
The Moon is 363 370 km (225 788 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 914 km (229 854 mi).
1 day after ascending node on 17 January 2043 at 04:57 in ♈ Aries the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 30 January 2043 at 09:53 in ♎ Libra.
8 days since the last southern standstill on 9 January 2043 at 20:09 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.311° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.367° at the point of next northern standstill on 22 January 2043 at 21:28 in ♊ Gemini.
1 day since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 25 January 2043 at 06:56 in ♌ Leo 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.
