First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 11 May 2057 at 21:06 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 leaving the last ∠1° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.
Next Full Moon is the Flower Moon of May 2057 after 6 days on 18 May 2057 at 19:02.
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 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1899".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 709 of Meeus index or 1662 from Brown series.
The length of this lunation is 29 days, 15 hours and 39 minutes and it is 3 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2057. 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 2 hours and 55 minutes longer than the mean synodic month length. It is 4 hours and 8 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 ∠148.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠173.3°.
5 days since point of apogee on 6 May 2057 at 19:52 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 19 May 2057 at 12:10 in ♐ Sagittarius.
The Moon is 389 839 km (242 235 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 926 km (222 405 mi).
4 days after ascending node on 7 May 2057 at 22:16 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 21 May 2057 at 03:05 in ♑ Capricorn.
3 days since the last northern standstill on 8 May 2057 at 14:10 in ♋ Cancer when the Moon has reached North declination of ∠23.611° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-23.658° at the point of next southern standstill on 21 May 2057 at 16:36 in ♑ Capricorn.
4 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 18 May 2057 at 19:02 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.
