Waning Gibbous on . The illuminated surface of the moon is 68% and getting smaller. The lunar cycle is 20 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠1° of ♒ Aquarius tropical zodiac sector and will enter ♓ Pisces later.
Previous main lunar phase is the Full Moon before 5 days on 5 June 2031 at 11:58.
Next Full Moon is the Buck Moon of July 2031 after 24 days on 4 July 2031 at 19:01.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 2.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1890".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 388 of Meeus index or 1341 from Brown series.
The length of this lunation is 29 days, 15 hours and 7 minutes and it is 9 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 2 hours and 23 minutes longer than the mean synodic month length. It is 4 hours and 40 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 ∠139.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠165.9°.
3 days since point of perigee on 6 June 2031 at 12:11 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 21 June 2031 at 11:25 in ♋ Cancer.
The Moon is 369 034 km (229 307 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 452 km (252 558 mi).
6 days after ascending node on 4 June 2031 at 09:20 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 17 June 2031 at 09:18 in ♉ Taurus.
4 days since the last southern standstill on 5 June 2031 at 17:57 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.099° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠21.105° at the point of next northern standstill on 19 June 2031 at 02:22 in ♊ Gemini.
6 days 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 9 days on 19 June 2031 at 22:25 in ♊ Gemini the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
