First Quarter on . The illuminated surface of the moon is 50% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 23 May 2045 at 12:38 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 ∠2° of ♍ Virgo tropical zodiac sector.
Next Full Moon is the Flower Moon of May 2045 after 7 days on 30 May 2045 at 17:52.
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 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1895".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 561 of Meeus index or 1514 from Brown series.
The length of this lunation is 29 days, 8 hours and 38 minutes and it is 1 hour and 14 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit 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 4 hours and 6 minutes shorter than the mean synodic month length. It is 2 hours and 3 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 ∠305.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠328°.
3 days since point of perigee on 20 May 2045 at 10:22 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 5 June 2045 at 03:25 in ♒ Aquarius.
The Moon is 364 650 km (226 583 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 694 km (251 465 mi).
Moon is in descending node in ♌ Leo at 02:17 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 5 June 2045 at 23:31 in ♒ Aquarius.
4 days since the last northern standstill on 18 May 2045 at 18:47 in ♊ Gemini when the Moon has reached North declination of ∠27.745° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-27.697° at the point of next southern standstill on 31 May 2045 at 22:23 in ♐ Sagittarius.
13 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 30 May 2045 at 17:52 in ♐ Sagittarius 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.
