First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 13 October 2040 at 08:41 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 ∠23° of ♑ Capricorn tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2040 after 6 days on 20 October 2040 at 04:50.
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 2.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1924".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 504 of Meeus index or 1457 from Brown series.
The length of this lunation is 29 days, 13 hours and 30 minutes and it is 53 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 46 minutes longer than the mean synodic month length. It is 6 hours and 17 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 ∠261.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠297°.
13 days since point of apogee on 30 September 2040 at 02:50 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 15 October 2040 at 11:20 in ♒ Aquarius.
The Moon is 363 565 km (225 909 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 368 986 km (229 277 mi).
4 days after descending node on 9 October 2040 at 08:33 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 22 October 2040 at 06:09 in ♉ Taurus.
1 day since the last southern standstill on 12 October 2040 at 12:03 in ♑ Capricorn when the Moon has reached South declination of ∠-26.728° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠26.789° at the point of next northern standstill on 25 October 2040 at 18:35 in ♋ Cancer.
18 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 20 October 2040 at 04:50 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.
