Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1893" and ∠1949".
Next Full Moon is the Wolf Moon of January 2018 after 22 days on 2 January 2018 at 02:24.

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 221 of Meeus index or 1174 from Brown series.
Length of current 221 lunation is 29 days, 18 hours and 48 minutes. It is 59 minutes shorter than next lunation 222 length.
Length of current synodic month is 6 hours and 4 minutes longer than the mean length of synodic month, but it is still 59 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠147°. At beginning of next synodic month true anomaly will be ∠173.3°. 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°).
6 days after point of perigee on 4 December 2017 at 08:42 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.

5 days after previous North standstill on 5 December 2017 at 11:43 in ♋ Cancer, when Moon has reached northern declination of ∠20.015°. Next 8 days the lunar orbit moves southward to face South declination of ∠-20.062° in the next southern standstill on 19 December 2017 at 09:31 in ♑ Capricorn.
After 7 days on 18 December 2017 at 06:31 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
