Previous main lunar phase is the Full Moon before 3 days on 18 April 2011 at 02:44.
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 ∠17° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 0.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1901" and ∠1909".
Next Full Moon is the Flower Moon of May 2011 after 25 days on 17 May 2011 at 11:09.
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 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 139 of Meeus index or 1092 from Brown series.
Length of current 139 lunation is 29 days, 16 hours and 18 minutes. It is 2 hours and 6 minutes longer than next lunation 140 length.
Length of current synodic month is 3 hours and 34 minutes longer than the mean length of synodic month, but it is still 3 hours and 29 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠190.9°. At the beginning of next synodic month true anomaly will be ∠216.7°. 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°).
4 days after point of perigee on 17 April 2011 at 05:59 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 29 April 2011 at 18:02 in ♓ Pisces.
Moon is 377 107 km (234 323 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 406 043 km (252 303 mi).
11 days after its descending node on 9 April 2011 at 12:48 in ♊ Gemini, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 22 April 2011 at 01:05 in ♐ Sagittarius.
26 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
At 13:40 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-23.498°. Next 14 days the lunar orbit will move in opposite northward direction to face North declination of ∠23.421° in its northern standstill point on 6 May 2011 at 03:54 in ♊ Gemini.
After 11 days on 3 May 2011 at 06:51 in ♉ Taurus, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
