First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 61% and growing larger. The 8 days young Moon is in ♉ Taurus.
* The exact date and time of this First Quarter phase is on 30 January 2031 at 07:43 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠24° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 8.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1785" and ∠1947".
Next Full Moon is the Snow Moon of February 2031 after 7 days on 7 February 2031 at 12:46.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 384 of Meeus index or 1337 from Brown series.
Length of current 384 lunation is 29 days, 11 hours and 18 minutes. It is 42 minutes shorter than next lunation 385 length.
Length of current synodic month is 1 hour and 26 minutes shorter than the mean length of synodic month, but it is still 4 hours and 43 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠21.6°. At beginning of next synodic month true anomaly will be ∠41.9°. 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 perigee on 21 January 2031 at 21:41 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.
Moon is 401 612 km (249 550 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 405 416 km (251 914 mi).
12 days after its ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.
12 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
11 days after previous South standstill on 20 January 2031 at 05:10 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.824°. Next 2 days the lunar orbit moves northward to face North declination of ∠21.745° in the next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.
After 7 days on 7 February 2031 at 12:46 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
