Gibbous ♑ Capricorn
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 55% and growing larger. The 8 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 11 September 2100 at 00:35 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠25° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1943" and ∠1906".
Next Full Moon is the Harvest Moon of September 2100 after 6 days on 18 September 2100 at 11:32.
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 1245 of Meeus index or 2198 from Brown series.
Length of current 1245 lunation is 29 days, 9 hours and 13 minutes. It is 1 minute longer than next lunation 1246 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 ∠320.8°. At the beginning of next synodic month true anomaly will be ∠340.4°. 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°).
4 days after point of perigee on 6 September 2100 at 19:23 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 22 September 2100 at 16:20 in ♉ Taurus.
Moon is 368 832 km (229 182 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 405 610 km (252 034 mi).
7 days after its descending node on 4 September 2100 at 02:42 in ♍ Virgo, 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 17 September 2100 at 01:56 in ♓ Pisces.
21 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
At 14:42 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.345°. Next 14 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.300° in its northern standstill point on 26 September 2100 at 01:39 in ♊ Gemini.
After 6 days on 18 September 2100 at 11:32 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
