First Quarter on . The illuminated surface of the moon is 58% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 27 September 2055 at 18:11 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 ∠14° of ♑ Capricorn tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2055 after 7 days on 5 October 2055 at 18:38.
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 2.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1864" and ∠1915".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 689 of Meeus index or 1642 from Brown series.
The length of this lunation is 29 days, 8 hours and 30 minutes and it is 1 hour and 15 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 4 hours and 14 minutes shorter than the mean synodic month length. It is 1 hour and 55 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 ∠352.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠7.9°.
6 days since point of perigee on 21 September 2055 at 12:32 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 5 October 2055 at 17:59 in ♈ Aries.
The Moon is 384 435 km (238 877 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 450 km (252 556 mi).
10 days after ascending node on 17 September 2055 at 19:18 in ♌ Leo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 30 September 2055 at 10:30 in ♒ Aquarius.
At 05:09 the Moon is meeting its standstill point to reach South declination of ∠-20.612°. Over the upcoming 14 days the lunar orbit is going to tilt northward to face maximum declination of ∠20.758° at the point of next northern standstill in ♋ Cancer on 13 October 2055 at 00:16.
10 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 5 October 2055 at 18:38 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.
