First Quarter on . The illuminated surface of the moon is 46% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 28 December 2090 at 21:36 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 ∠3° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Wolf Moon of January 2091 after 8 days on 5 January 2091 at 15:50.
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 9.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1951".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1125 of Meeus index or 2078 from Brown series.
The length of this lunation is 29 days, 15 hours and 2 minutes and it is 2 hours 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 2 hours and 18 minutes longer than the mean synodic month length. It is 4 hours and 45 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 ∠65.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠102°.
Moon is at apogee at 17:47 about 12 days since last perigee on 16 December 2090 at 06:21 in ♎ Libra the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 9 January 2091 at 22:29 in ♍ Virgo.
This apogee Moon is 404 274 km (251 204 mi) away from Earth. It is 1 134 km further than the mean apogee distance, but it is still 2 435 km closer than the farthest apogee of 21st century.
1 day after descending node on 26 December 2090 at 22:11 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 9 January 2091 at 17:43 in ♍ Virgo.
7 days since the last southern standstill on 21 December 2090 at 09:02 in ♑ Capricorn when the Moon has reached South declination of ∠-18.635° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠18.625° at the point of next northern standstill on 4 January 2091 at 20:03 in ♊ Gemini.
14 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 8 days on 5 January 2091 at 15:50 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.
