Quarter ♎ Libra
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 46% and growing larger. The 7 days young Moon is in ♎ Libra.
* The exact date and time of this First Quarter phase is on 15 July 2051 at 23:21 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠18° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1888".
Next Full Moon is the Buck Moon of July 2051 after 8 days on 23 July 2051 at 16:36.
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 637 of Meeus index or 1590 from Brown series.
Length of current 637 lunation is 29 days, 10 hours and 56 minutes. It is 2 hours and 32 minutes shorter than next lunation 638 length.
Length of current synodic month is 1 hour and 48 minutes shorter than the mean length of synodic month, but it is still 4 hours and 21 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠70.2°. At beginning of next synodic month true anomaly will be ∠104.1°. 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°).
Moon is reaching point of apogee on this date at 16:49, this is 12 days after last perigee on 2 July 2051 at 20:59 in ♈ Aries. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 28 July 2051 at 00:46 in ♈ Aries.
This apogee Moon is 404 065 km (251 074 mi) away from Earth. This is the year's closest apogee of 2051. It is 1 343 km farther than the mean apogee distance, but it is still 14 km closer than the farthest apogee of 21st century.
12 days after its descending node on 2 July 2051 at 17:54 in ♈ Aries, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 16 July 2051 at 09:35 in ♎ Libra.
26 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
9 days after previous North standstill on 6 July 2051 at 11:58 in ♊ Gemini, when Moon has reached northern declination of ∠19.198°. Next 5 days the lunar orbit moves southward to face South declination of ∠-19.133° in the next southern standstill on 20 July 2051 at 20:52 in ♐ Sagittarius.
After 8 days on 23 July 2051 at 16:36 in ♑ Capricorn, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
