Waxing Gibbous on . The illuminated surface of the moon is 72% and growing larger. The lunar cycle is 9 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is passing first ∠3° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the First Quarter before 2 days on 27 July 2031 at 10:35.
Next Full Moon is the Sturgeon Moon of August 2031 after 4 days on 3 August 2031 at 01:45.
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 2.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1943" and ∠1890".
The Moon is 9 days young and navigating from the first to the middle part of the current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.
The length of this lunation is 29 days, 14 hours and 52 minutes and it is 37 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 2 hours and 8 minutes longer than the mean synodic month length. It is 4 hours and 55 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 ∠188.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠213.5°.
10 days since point of apogee on 18 July 2031 at 14:28 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 2 August 2031 at 06:47 in ♑ Capricorn.
The Moon is 368 835 km (229 183 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 358 060 km (222 488 mi).
1 day after ascending node on 28 July 2031 at 23:54 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 10 August 2031 at 14:10 in ♉ Taurus.
13 days since the last northern standstill on 16 July 2031 at 09:01 in ♊ Gemini when the Moon has reached North declination of ∠21.045° the lunar orbit is extending southward over the next day to face maximum declination of ∠-20.951° at the point of next southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius.
1 day since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 4 days on 3 August 2031 at 01:45 in ♒ Aquarius 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.
