Previous main lunar phase is the Full Moon before 2 days on 28 January 2021 at 19:16.
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 ∠16° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1928" and ∠1947".
Next Full Moon is the Snow Moon of February 2021 after 26 days on 27 February 2021 at 08:17.
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 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 260 of Meeus index or 1213 from Brown series.
Length of current 260 lunation is 29 days, 14 hours and 5 minutes. It is 1 hour and 10 minutes shorter than next lunation 261 length.
Length of current synodic month is 1 hour and 21 minutes longer than the mean length of synodic month, but it is still 5 hours and 42 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠53.8°. At beginning of next synodic month true anomaly will be ∠87°. 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°).
9 days after point of apogee on 21 January 2021 at 13:11 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 3 February 2021 at 19:33 in ♎ Libra.
Moon is 371 729 km (230 982 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 370 127 km (229 986 mi).
6 days after its ascending node on 24 January 2021 at 21:47 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 7 February 2021 at 00:29 in ♐ Sagittarius.
6 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the beginning to the first part of it.
4 days after previous North standstill on 26 January 2021 at 15:39 in ♋ Cancer, when Moon has reached northern declination of ∠24.898°. Next 8 days the lunar orbit moves southward to face South declination of ∠-24.953° in the next southern standstill on 8 February 2021 at 15:34 in ♑ Capricorn.
After 11 days on 11 February 2021 at 19:06 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
