First Quarter on . The illuminated surface of the moon is 57% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 29 April 2031 at 19:19 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠18° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Flower Moon of May 2031 after 6 days on 7 May 2031 at 03:40.
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.
Lunar disc appears visually 6.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1791" and ∠1905".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 387 of Meeus index or 1340 from Brown series.
The length of this lunation is 29 days, 14 hours and 20 minutes and it is 47 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 36 minutes longer than the mean synodic month length. It is 5 hours and 27 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠106.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠139.8°.
3 days since point of apogee on 27 April 2031 at 10:30 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 9 May 2031 at 07:28 in ♐ Sagittarius.
The Moon is 400 236 km (248 695 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 362 851 km (225 465 mi).
6 days after descending node on 23 April 2031 at 20:23 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 7 May 2031 at 22:55 in ♏ Scorpio.
4 days since the last northern standstill on 25 April 2031 at 12:37 in ♊ Gemini when the Moon has reached North declination of ∠21.107° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-21.092° at the point of next southern standstill on 9 May 2031 at 07:56 in ♐ Sagittarius.
19 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 7 May 2031 at 03:40 in ♏ Scorpio 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.
