* The exact date and time of this First Quarter phase is on 21 March 2021 at 14:40 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠0° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1795" and ∠1926".
Next Full Moon is the Worm Moon of March 2021 after 7 days on 28 March 2021 at 18:48.
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 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 262 of Meeus index or 1215 from Brown series.
Length of current 262 lunation is 29 days, 16 hours and 10 minutes. It is 19 minutes shorter than next lunation 263 length.
Length of current synodic month is 3 hours and 26 minutes longer than the mean length of synodic month, but it is still 3 hours and 37 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠124.3°. At beginning of next synodic month true anomaly will be ∠154.8°. 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°).
3 days after point of apogee on 18 March 2021 at 05:04 in ♉ Taurus. 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 30 March 2021 at 06:12 in ♏ Scorpio.
Moon is 399 363 km (248 153 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 360 311 km (223 887 mi).
1 day after its ascending node on 20 March 2021 at 03:31 in ♊ Gemini, 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 2 April 2021 at 02:41 in ♐ Sagittarius.

13 days after previous South standstill on 7 March 2021 at 20:45 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.161°. Next day the lunar orbit moves northward to face North declination of ∠25.307° in the next northern standstill on 22 March 2021 at 08:35 in ♋ Cancer.
After 7 days on 28 March 2021 at 18:48 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
