Waning Crescent on . The illuminated surface of the moon is 8% and getting smaller. The lunar cycle is 26 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing about ∠25° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 4 days on 13 May 2031 at 19:07.
Next Full Moon is the Strawberry Moon of June 2031 after 17 days on 5 June 2031 at 11:58.
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 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1843" and ∠1897".
The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 387 of Meeus index or 1340 from Brown series.
The length of this lunation is 29 days, 14 hours and 20 minutes and it is 47 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 1 hour and 36 minutes longer than the mean synodic month length. It is 5 hours and 27 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 ∠106.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠139.8°.
9 days since point of perigee on 9 May 2031 at 07:28 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 6 days until the Moon reaches the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.
The Moon is 388 935 km (241 673 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 405 723 km (252 105 mi).
10 days after ascending node on 7 May 2031 at 22:55 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.
9 days since the last southern standstill on 9 May 2031 at 07:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.092° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠21.091° at the point of next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.
10 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 2 days on 21 May 2031 at 07:17 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.
