Quarter ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and growing larger. The 8 days young Moon is in ♓ Pisces.
* The exact date and time of this First Quarter phase is on 17 December 2026 at 05:43 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is leaving the last ∠1° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Lunar disc appears visually 5.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1850" and ∠1950".
Next Full Moon is the Cold Moon of December 2026 after 6 days on 24 December 2026 at 01:28.
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.
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 333 of Meeus index or 1286 from Brown series.
The length of the lunation is 29 days, 19 hours and 33 minutes. This is the year's longest synodic month of 2026. It is 1 minute longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 6 hours and 48 minutes longer than the mean synodic month length. It is 14 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠159.4°. At the beginning of next synodic month the true anomaly is going to be ∠184.3°.
6 days after point of apogee on 11 December 2026 at 06:46 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 24 December 2026 at 08:30 in ♋ Cancer.
The Moon is 387 416 km (240 729 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 650 km (221 612 mi).
2 days after ascending node on 14 December 2026 at 13:04 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 27 December 2026 at 07:55 in ♌ Leo.
2 days since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.
7 days since the previous standstill on 9 December 2026 at 15:27 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.602°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠27.620° at the point of next northern standstill on 23 December 2026 at 12:33 in ♊ Gemini.
In 6 days on 24 December 2026 at 01:28 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.
