Quarter ♍ Virgo
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 49% and growing larger. The 7 days young Moon is in ♌ Leo.
* The exact date and time of this First Quarter phase is on 17 May 2051 at 13:29 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 5.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1802" and ∠1897".
Next Full Moon is the Flower Moon of May 2051 after 8 days on 25 May 2051 at 17:35.
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 635 of Meeus index or 1588 from Brown series.
Length of current 635 lunation is 29 days, 8 hours and 27 minutes. This is the year's shortest synodic month of 2051. It is 46 minutes shorter than next lunation 636 length.
Length of current synodic month is 4 hours and 17 minutes shorter than the mean length of synodic month, but it is still 1 hour and 52 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠23.1°. At beginning of next synodic month true anomaly will be ∠43.2°. 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°).
8 days after point of perigee on 9 May 2051 at 01:26 in ♈ Aries. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 21 May 2051 at 04:56 in ♎ Libra.
Moon is 397 838 km (247 205 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 405 251 km (251 811 mi).
8 days after its descending node on 9 May 2051 at 06:46 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 23 May 2051 at 02:03 in ♏ Scorpio.
21 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the second to the final part of it.
4 days after previous North standstill on 12 May 2051 at 15:20 in ♊ Gemini, when Moon has reached northern declination of ∠19.181°. Next 9 days the lunar orbit moves southward to face South declination of ∠-19.213° in the next southern standstill on 27 May 2051 at 03:09 in ♐ Sagittarius.
After 8 days on 25 May 2051 at 17:35 in ♏ Scorpio, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
