Gibbous ♐ Sagittarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 62% and growing larger. The 8 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 27 July 2031 at 10:35 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠19° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 1.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1924" and ∠1890".
Next Full Moon is the Sturgeon Moon of August 2031 after 5 days on 3 August 2031 at 01:45.
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 390 of Meeus index or 1343 from Brown series.
The length of the lunation is 29 days, 14 hours and 52 minutes. It is 37 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 8 minutes longer than the mean synodic month length. It is 4 hours and 55 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠188.7°. At the beginning of next synodic month the true anomaly is going to be ∠213.5°.
9 days after point of apogee on 18 July 2031 at 14:28 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 2 August 2031 at 06:47 in ♑ Capricorn.
The Moon is 372 623 km (231 537 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 358 060 km (222 488 mi).
Moon is in ascending node in ♏ Scorpio at 23:54 crossing the ecliptic from South to North to meet descending node 13 days later on 10 August 2031 at 14:10 in ♉ Taurus.
At 23:54 the Moon completes the previous draconic month and enters the new one.
12 days since the previous standstill on 16 July 2031 at 09:01 in ♊ Gemini when the Moon has reached North declination of ∠21.045°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-20.951° at the point of next southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius.
In 5 days on 3 August 2031 at 01:45 in ♒ Aquarius 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.
