Waning Gibbous on . The illuminated surface of the moon is 90% and getting smaller. The lunar cycle is 17 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠25° of ♌ Leo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 5 January 2091 at 15:50.
Next Full Moon is the Snow Moon of February 2091 after 26 days on 4 February 2091 at 04:46.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1946" and ∠1951".
The Moon is 17 days old and navigating from the middle to the last 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°.
10 days since point of apogee on 28 December 2090 at 17:47 in ♓ Pisces 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 9 January 2091 at 22:29 in ♍ Virgo.
The Moon is 368 262 km (228 827 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 368 696 km (229 097 mi).
12 days after descending node on 26 December 2090 at 22:11 in ♓ Pisces the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 9 January 2091 at 17:43 in ♍ Virgo.
3 days since the last northern standstill on 4 January 2091 at 20:03 in ♊ Gemini when the Moon has reached North declination of ∠18.625° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-18.589° at the point of next southern standstill on 17 January 2091 at 18:01 in ♐ Sagittarius.
25 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 11 days on 19 January 2091 at 16:31 in ♑ Capricorn the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
