Quarter ♑ Capricorn
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 13 September 2051 at 09:20 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠22° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1812" and ∠1907".
Next Full Moon is the Harvest Moon of September 2051 after 6 days on 20 September 2051 at 10:11.
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 639 of Meeus index or 1592 from Brown series.
Length of current 639 lunation is 29 days, 16 hours and 14 minutes. It is 1 hour and 58 minutes shorter than next lunation 640 length.
Length of current synodic month is 3 hours and 29 minutes longer than the mean length of synodic month, but it is still 3 hours and 33 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠137°. At beginning of next synodic month true anomaly will be ∠163.9°. 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°).
4 days after point of apogee on 9 September 2051 at 04:18 in ♏ Scorpio. 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 21 September 2051 at 12:20 in ♈ Aries.
Moon is 395 598 km (245 813 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 358 920 km (223 023 mi).
4 days after its ascending node on 8 September 2051 at 15:18 in ♎ Libra, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 22 September 2051 at 03:59 in ♈ Aries.
4 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the beginning to the first part of it.
At 15:30 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-18.758°. Next 12 days the lunar orbit will move in opposite northward direction to face North declination of ∠18.704° in its northern standstill point on 26 September 2051 at 07:36 in ♊ Gemini.
After 6 days on 20 September 2051 at 10:11 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
