Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and getting smaller. The 21 days old Moon is in ♓ Pisces.
* The exact date and time of this Last Quarter phase is on 31 May 2013 at 18:58 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠7° of ♓ Pisces tropical zodiac sector.
Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1911" and ∠1892".
Next Full Moon is the Strawberry Moon of June 2013 after 22 days on 23 June 2013 at 11:32.
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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 165 of Meeus index or 1118 from Brown series.
Length of current 165 lunation is 29 days, 15 hours and 28 minutes. This is the year's longest synodic month of 2013. It is 10 minutes longer than next lunation 166 length.
Length of current synodic month is 2 hours and 44 minutes longer than the mean length of synodic month, but it is still 4 hours and 19 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠143.3°. At beginning of next synodic month true anomaly will be ∠168.8°. 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°).
5 days after point of perigee on 26 May 2013 at 01:45 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 9 June 2013 at 21:40 in ♊ Gemini.
Moon is 375 139 km (233 101 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 406 487 km (252 579 mi).
7 days after its ascending node on 24 May 2013 at 00:40 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 6 June 2013 at 00:59 in ♉ Taurus.
7 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
5 days after previous South standstill on 26 May 2013 at 04:47 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.182°. Next 8 days the lunar orbit moves northward to face North declination of ∠20.200° in the next northern standstill on 8 June 2013 at 19:16 in ♊ Gemini.
After 8 days on 8 June 2013 at 15:56 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
