Previous main lunar phase is the Full Moon before 5 days on 7 May 2031 at 03:40.
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.
Moon is passing about ∠5° of ♒ Aquarius tropical zodiac sector.
Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1899".
Next Full Moon is the Strawberry Moon of June 2031 after 23 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.
The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 387 of Meeus index or 1340 from Brown series.
Length of current 387 lunation is 29 days, 14 hours and 20 minutes. It is 47 minutes shorter than next lunation 388 length.
Length of current synodic month is 1 hour and 36 minutes longer than the mean length of synodic month, but it is still 5 hours and 27 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠106.4°. At beginning of next synodic month true anomaly will be ∠139.8°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
3 days after point of perigee on 9 May 2031 at 07:28 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.
Moon is 365 000 km (226 800 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 405 723 km (252 105 mi).
4 days after its ascending node on 7 May 2031 at 22:55 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.
4 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
3 days after previous South standstill on 9 May 2031 at 07:56 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.092°. Next 10 days the lunar orbit moves northward to face North declination of ∠21.091° in the next northern standstill on 22 May 2031 at 19:41 in ♊ Gemini.
After 8 days on 21 May 2031 at 07:17 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
