First Quarter on . The illuminated surface of the moon is 45% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 26 August 2039 at 23:16 UTC.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠3° of ♏ Scorpio tropical zodiac sector and will enter ♐ Sagittarius later.
Next Full Moon is the Harvest Moon of September 2039 after 7 days on 2 September 2039 at 19:23.
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 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1899".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 490 of Meeus index or 1443 from Brown series.
The length of this lunation is 29 days, 11 hours and 32 minutes and it is 46 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 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 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 ∠260.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠294.5°.
12 days since point of apogee on 13 August 2039 at 19:35 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 29 August 2039 at 03:16 in ♑ Capricorn.
The Moon is 364 384 km (226 418 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 368 737 km (229 123 mi).
12 days after ascending node on 14 August 2039 at 10:57 in ♊ Gemini 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 28 August 2039 at 01:19 in ♐ Sagittarius.
10 days since the last northern standstill on 16 August 2039 at 04:38 in ♋ Cancer when the Moon has reached North declination of ∠24.786° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-24.880° at the point of next southern standstill on 29 August 2039 at 14:11 in ♑ Capricorn.
12 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 7 days on 2 September 2039 at 19:23 in ♓ Pisces 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.
