Previous main lunar phase is the Last Quarter before 3 days on 13 May 2031 at 19:07.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Moon is passing about ∠12° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1865" and ∠1897".
Next Full Moon is the Strawberry Moon of June 2031 after 18 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.
The Moon is 25 days old. Earth's natural satellite is moving from the second to the final 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°).
8 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 7 days, until it get to the point of next apogee on 25 May 2031 at 02:08 in ♋ Cancer.
Moon is 384 241 km (238 756 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 405 723 km (252 105 mi).
9 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 3 days, until it will cross the ecliptic from North to South in descending node on 21 May 2031 at 03:26 in ♉ Taurus.
9 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
8 days after previous South standstill on 9 May 2031 at 07:56 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.092°. Next 5 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 3 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.
