Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1950".
Next Full Moon is the Wolf Moon of January 2100 after 8 days on 26 January 2100 at 02:49.
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 6 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 1237 of Meeus index or 2190 from Brown series.
Length of current 1237 lunation is 29 days, 15 hours and 59 minutes. It is 1 hour and 35 minutes shorter than next lunation 1238 length.
Length of current synodic month is 3 hours and 15 minutes longer than the mean length of synodic month, but it is still 3 hours and 48 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠81.3°. At beginning of next synodic month true anomaly will be ∠119.1°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon is reaching point of apogee on this date at 10:48, this is 14 days after last perigee on 3 January 2100 at 08:57 in ♎ Libra. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 11 days ahead, until it will get to the point of next perigee on 29 January 2100 at 05:53 in ♍ Virgo.
This apogee Moon is 404 420 km (251 295 mi) away from Earth. It is 988 km farther than the mean apogee distance, but it is still 2 289 km closer than the farthest apogee of 21st century.
2 days after its ascending node on 15 January 2100 at 03:56 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 29 January 2100 at 00:35 in ♍ Virgo.

8 days after previous South standstill on 8 January 2100 at 21:59 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.379°. Next 5 days the lunar orbit moves northward to face North declination of ∠28.437° in the next northern standstill on 23 January 2100 at 08:16 in ♊ Gemini.
After 8 days on 26 January 2100 at 02:49 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
