Quarter ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 47% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 21 August 2091 at 17:43 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1897".
Next Full Moon is the Sturgeon Moon of August 2091 after 7 days on 29 August 2091 at 00:39.
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 1133 of Meeus index or 2086 from Brown series.
Length of current 1133 lunation is 29 days, 9 hours and 13 minutes. It is 19 minutes longer than next lunation 1134 length.
Length of current synodic month is 3 hours and 31 minutes shorter than the mean length of synodic month, but it is still 2 hours and 38 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠310.2°. At the beginning of next synodic month true anomaly will be ∠332.3°. 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°).
3 days after point of perigee on 18 August 2091 at 06:08 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 3 September 2091 at 01:49 in ♉ Taurus.
Moon is 364 893 km (226 734 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 405 142 km (251 744 mi).
5 days after its ascending node on 15 August 2091 at 17:38 in ♌ Leo, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 28 August 2091 at 18:22 in ♒ Aquarius.
5 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
9 days after previous North standstill on 11 August 2091 at 15:21 in ♋ Cancer, when Moon has reached northern declination of ∠18.890°. Next 2 days the lunar orbit moves southward to face South declination of ∠-18.873° in the next southern standstill on 24 August 2091 at 11:30 in ♑ Capricorn.
After 7 days on 29 August 2091 at 00:39 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
