First Quarter on . The illuminated surface of the moon is 57% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 27 January 2091 at 19:23 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 ∠16° of ♉ Taurus tropical zodiac sector.
Next Full Moon is the Snow Moon of February 2091 after 6 days on 4 February 2091 at 04:46.
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 8.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1788" and ∠1948".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1126 of Meeus index or 2079 from Brown series.
The length of this lunation is 29 days, 17 hours and 7 minutes and it is 1 hour 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 23 minutes longer than the mean synodic month length. It is 2 hours and 40 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 ∠102° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠137.9°.
2 days since point of apogee on 25 January 2091 at 14:57 in ♈ Aries 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 6 February 2091 at 09:12 in ♍ Virgo.
The Moon is 400 776 km (249 031 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 363 106 km (225 624 mi).
5 days after descending node on 23 January 2091 at 02:24 in ♓ Pisces 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 5 February 2091 at 23:52 in ♍ Virgo.
10 days since the last southern standstill on 17 January 2091 at 18:01 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.589° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠18.537° at the point of next northern standstill on 1 February 2091 at 06:49 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 6 days on 4 February 2091 at 04:46 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.
