Previous main lunar phase is the Full Moon before 6 days on 17 May 2011 at 11:09.
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 ∠18° of ♒ Aquarius tropical zodiac sector.
Lunar disc appears visually 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1804" and ∠1895".
Next Full Moon is the Strawberry Moon of June 2011 after 23 days on 15 June 2011 at 20:13.
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 from the middle to the last part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.
Length of current 140 lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than next lunation 141 length.
Length of current synodic month is 1 hour and 28 minutes longer than the mean length of synodic month, but it is still 5 hours and 35 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠216.7°. At the beginning of next synodic month true anomaly will be ∠248.4°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
8 days after point of perigee on 15 May 2011 at 11:18 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.
Moon is 397 388 km (246 925 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 405 006 km (251 659 mi).
4 days after its ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 2 June 2011 at 20:21 in ♊ Gemini.
4 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
4 days after previous South standstill on 18 May 2011 at 23:26 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.403°. Next 9 days the lunar orbit moves northward to face North declination of ∠23.393° in the next northern standstill on 2 June 2011 at 09:54 in ♊ Gemini.
After 9 days on 1 June 2011 at 21:03 in ♊ Gemini, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
