First Quarter on . The illuminated surface of the moon is 53% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 6 January 2055 at 03:39 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 2055 after 6 days on 13 January 2055 at 11:21.
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 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1951".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 680 of Meeus index or 1633 from Brown series.
The length of this lunation is 29 days, 17 hours and 47 minutes and it is 1 hour and 13 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 5 hours and 3 minutes longer than the mean synodic month length. It is 2 hours 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 ∠109.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠143.9°.
2 days since point of apogee on 3 January 2055 at 13:48 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 15 January 2055 at 09:13 in ♌ Leo.
The Moon is 400 547 km (248 888 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 362 045 km (224 964 mi).
5 days after descending node on 1 January 2055 at 10:10 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 January 2055 at 05:53 in ♌ Leo.
8 days since the last southern standstill on 29 December 2054 at 03:18 in ♑ Capricorn when the Moon has reached South declination of ∠-19.763° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.742° at the point of next northern standstill on 12 January 2055 at 12:37 in ♋ Cancer.
18 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 13 January 2055 at 11:21 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.
