First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 58% and growing larger. The 8 days young Moon is in ♍ Virgo.
* The exact date and time of this First Quarter phase is on 19 May 2021 at 19:13 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠8° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1897" and ∠1896".
Next Full Moon is the Flower Moon of May 2021 after 5 days on 26 May 2021 at 11:14.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 264 of Meeus index or 1217 from Brown series.
Length of current 264 lunation is 29 days, 15 hours and 53 minutes. It is 1 hour and 29 minutes longer than next lunation 265 length.
Length of current synodic month is 3 hours and 9 minutes longer than the mean length of synodic month, but it is still 3 hours and 54 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠178.9°. At the beginning of next synodic month true anomaly will be ∠202.3°. 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°).
8 days after point of apogee on 11 May 2021 at 21:54 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 26 May 2021 at 01:52 in ♏ Scorpio.
Moon is 377 861 km (234 792 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 357 310 km (222 022 mi).
7 days after its ascending node on 13 May 2021 at 10:29 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 26 May 2021 at 19:38 in ♐ Sagittarius.
7 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 15 May 2021 at 22:25 in ♋ Cancer, when Moon has reached northern declination of ∠25.640°. Next 8 days the lunar orbit moves southward to face South declination of ∠-25.647° in the next southern standstill on 28 May 2021 at 19:21 in ♑ Capricorn.
After 5 days on 26 May 2021 at 11:14 in ♐ Sagittarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
