Waxing Gibbous on . The illuminated surface of the moon is 75% and growing larger. The lunar cycle is 10 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠1° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Previous main lunar phase is the First Quarter before 2 days on 17 December 2091 at 17:29.
Next Full Moon is the Cold Moon of December 2091 after 5 days on 25 December 2091 at 21:59.
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 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1950".
The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 1137 of Meeus index or 2090 from Brown series.
The length of this lunation is 29 days, 11 hours and 43 minutes and it is 1 hour and 43 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 1 hour and 1 minute shorter than the mean synodic month length. It is 5 hours and 8 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠20.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠40.9°.
11 days since point of perigee on 9 December 2091 at 08:19 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 21 December 2091 at 10:59 in ♉ Taurus.
The Moon is 404 636 km (251 429 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 544 km (251 993 mi).
5 days after descending node on 15 December 2091 at 07:03 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 29 December 2091 at 20:00 in ♌ Leo.
8 days since the last southern standstill on 11 December 2091 at 21:10 in ♑ Capricorn when the Moon has reached South declination of ∠-19.452° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠19.486° at the point of next northern standstill on 26 December 2091 at 05:43 in ♋ Cancer.
17 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 5 days on 25 December 2091 at 21:59 in ♊ Gemini 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.
