Previous main lunar phase is the Full Moon before 6 days on 6 January 2023 at 23:08.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing about ∠5° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1951".
Next Full Moon is the Snow Moon of February 2023 after 23 days on 5 February 2023 at 18:29.
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 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 284 of Meeus index or 1237 from Brown series.
Length of current 284 lunation is 29 days, 10 hours and 36 minutes. This is the year's shortest synodic month of 2023. It is 23 minutes longer than next lunation 285 length.
Length of current synodic month is 2 hours and 8 minutes shorter than the mean length of synodic month, but it is still 4 hours and 1 minute longer, compared to 21st century shortest.
This lunation true anomaly is ∠344.3°. At the beginning of next synodic month true anomaly will be ∠360°. 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°).
5 days after point of apogee on 8 January 2023 at 09:19 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 21 January 2023 at 20:58 in ♑ Capricorn.
Moon is 392 870 km (244 118 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 356 570 km (221 562 mi).
11 days after its ascending node on 1 January 2023 at 15:25 in ♉ Taurus, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 16 January 2023 at 06:32 in ♏ Scorpio.
11 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the beginning to the first part of it.
7 days after previous North standstill on 6 January 2023 at 03:08 in ♋ Cancer, when Moon has reached northern declination of ∠27.406°. Next 6 days the lunar orbit moves southward to face South declination of ∠-27.461° in the next southern standstill on 20 January 2023 at 05:06 in ♑ Capricorn.
After 8 days on 21 January 2023 at 20:53 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
