First Quarter on . The illuminated surface of the moon is 61% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 8 December 2081 at 06:38 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 ∠1° of ♈ Aries tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2081 after 6 days on 16 December 2081 at 04:31.
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 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1949".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1013 of Meeus index or 1966 from Brown series.
The length of this lunation is 29 days, 13 hours and 52 minutes and it is 2 hours and 26 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 8 minutes longer than the mean synodic month length. It is 5 hours and 55 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 ∠52.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠84.8°.
Moon is at apogee at 00:48 about 11 days since last perigee on 27 November 2081 at 03:46 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 22 December 2081 at 10:49 in ♍ Virgo.
This apogee Moon is 404 288 km (251 213 mi) away from Earth. It is 1 120 km further than the mean apogee distance, but it is still 2 421 km closer than the farthest apogee of 21st century.
1 day after ascending node on 7 December 2081 at 17:00 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 21 December 2081 at 12:04 in ♍ Virgo.
7 days since the last southern standstill on 1 December 2081 at 21:51 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.151° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.126° at the point of next northern standstill on 16 December 2081 at 08:03 in ♊ Gemini.
1 day since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 16 December 2081 at 04:31 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.
