Previous main lunar phase is the First Quarter before 3 days on 18 May 2013 at 04:35.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠11° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1893" and ∠1895".
Next Full Moon is the Flower Moon of May 2013 after 3 days on 25 May 2013 at 04:25.
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 10 days young. Earth's natural satellite is moving from the first to the middle 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°).
7 days after point of apogee on 13 May 2013 at 13:31 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 26 May 2013 at 01:45 in ♐ Sagittarius.
Moon is 378 553 km (235 222 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 358 375 km (222 684 mi).
11 days after its descending node on 9 May 2013 at 19:12 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 24 May 2013 at 00:40 in ♏ Scorpio.
24 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 12 May 2013 at 12:30 in ♊ Gemini, when Moon has reached northern declination of ∠20.170°. Next 4 days the lunar orbit moves southward to face South declination of ∠-20.182° in the next southern standstill on 26 May 2013 at 04:47 in ♐ Sagittarius.
After 3 days on 25 May 2013 at 04:25 in ♐ Sagittarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
