Previous main lunar phase is the Last Quarter before 4 days on 16 December 2087 at 20:11.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Moon is passing about ∠21° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1951".
Next Full Moon is the Wolf Moon of January 2088 after 17 days on 8 January 2088 at 09:37.
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.
The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 1087 of Meeus index or 2040 from Brown series.
Length of current 1087 lunation is 29 days, 19 hours and 19 minutes. This is the year's longest synodic month of 2087. It is 1 hour and 23 minutes longer than next lunation 1088 length.
Length of current synodic month is 6 hours and 35 minutes longer than the mean length of synodic month, but it is still 28 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠183°. At the beginning of next synodic month true anomaly will be ∠208.8°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
12 days after point of perigee on 9 December 2087 at 08:50 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 22 December 2087 at 02:07 in ♏ Scorpio.
Moon is 405 064 km (251 695 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 406 133 km (252 359 mi).
Moon is in ascending node in ♏ Scorpio at 00:25 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 4 January 2088 at 02:18 in ♉ Taurus.
At 00:25 on this date the Moon is completing its previous draconic month and is entering the new one.
11 days after previous North standstill on 10 December 2087 at 01:14 in ♊ Gemini, when Moon has reached northern declination of ∠20.072°. Next 2 days the lunar orbit moves southward to face South declination of ∠-20.078° in the next southern standstill on 23 December 2087 at 22:55 in ♐ Sagittarius.
After 3 days on 25 December 2087 at 01:42 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
