First Quarter on . The illuminated surface of the moon is 54% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 18 September 2045 at 01:30 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 ∠1° of ♑ Capricorn tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2045 after 7 days on 26 September 2045 at 06:11.
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 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1807" and ∠1910".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 565 of Meeus index or 1518 from Brown series.
The length of this lunation is 29 days, 9 hours and 9 minutes and it is 2 hours 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 3 hours and 35 minutes shorter than the mean synodic month length. It is 2 hours and 34 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 ∠16.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠34.3°.
8 days since point of perigee on 10 September 2045 at 02:20 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 22 September 2045 at 12:20 in ♒ Aquarius.
The Moon is 396 657 km (246 471 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 498 km (251 965 mi).
9 days after descending node on 9 September 2045 at 07:56 in ♌ Leo the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 22 September 2045 at 19:34 in ♒ Aquarius.
1 day since the last southern standstill on 17 September 2045 at 22:27 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.716° the lunar orbit is extending northward over the next 14 days to face maximum declination of ∠27.609° at the point of next northern standstill on 2 October 2045 at 12:33 in ♊ Gemini.
22 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 26 September 2045 at 06:11 in ♈ Aries 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.
