First Quarter on . The illuminated surface of the moon is 46% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 27 April 2023 at 21:20 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 first ∠3° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Flower Moon of May 2023 after 8 days on 5 May 2023 at 17:34.
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 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1906".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 288 of Meeus index or 1241 from Brown series.
The length of this lunation is 29 days, 11 hours and 41 minutes and it is 1 hour and 3 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 3 minutes shorter than the mean synodic month length. It is 5 hours and 6 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠59.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠92.6°.
11 days since point of perigee on 16 April 2023 at 02:22 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 28 April 2023 at 06:43 in ♌ Leo.
The Moon is 405 160 km (251 755 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 300 km (251 220 mi).
7 days after ascending node on 20 April 2023 at 11:32 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 4 May 2023 at 21:57 in ♎ Libra.
2 days since the last northern standstill on 25 April 2023 at 05:53 in ♋ Cancer when the Moon has reached North declination of ∠27.957° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-27.937° at the point of next southern standstill on 9 May 2023 at 09:01 in ♑ Capricorn.
7 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.
In 8 days on 5 May 2023 at 17:34 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.
