Waning Gibbous on . The illuminated surface of the moon is 92% and getting smaller. The lunar cycle is 17 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 passing about ∠21° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 7 May 2031 at 03:40.
Next Full Moon is the Strawberry Moon of June 2031 after 26 days on 5 June 2031 at 11:58.
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 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1900".
The Moon is 17 days old and navigating from the middle to the last 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°.
Moon is at perigee at 07:28 about 11 days since last apogee on 27 April 2031 at 10:30 in ♋ Cancer the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.
This perigee Moon is 362 851 km (225 465 mi) away from Earth. It is 343 km closer than the mean perigee distance, but it is still 7 505 km further than the closest perigee of 21st century.
1 day after ascending node on 7 May 2031 at 22:55 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.
At 07:56 the Moon is meeting its standstill point to reach South declination of ∠-21.092°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠21.091° at the point of next northern standstill in ♊ Gemini on 22 May 2031 at 19:41.
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 11 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.
