Quarter ♑ Capricorn
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 ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 13 September 2021 at 20:39 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠16° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1907".
Next Full Moon is the Harvest Moon of September 2021 after 7 days on 20 September 2021 at 23:55.
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 268 of Meeus index or 1221 from Brown series.
The length of the lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠297.8°. At the beginning of next synodic month the true anomaly is going to be ∠323.3°.
2 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 13 days, until the Moon reaches the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.
The Moon is 363 588 km (225 923 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 641 km (251 432 mi).
1 day after descending node on 12 September 2021 at 16:35 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 12 days, until the lunar orbit crosses from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.
14 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.
11 days since the previous standstill on 2 September 2021 at 00:23 in ♋ Cancer when the Moon has reached North declination of ∠25.868°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-25.980° at the point of next southern standstill on 15 September 2021 at 03:48 in ♑ Capricorn.
In 7 days on 20 September 2021 at 23:55 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
