Previous main lunar phase is the Full Moon before 5 days on 15 July 2011 at 06:40.
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.
Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1888".
Next Full Moon is the Sturgeon Moon of August 2011 after 24 days on 13 August 2011 at 18:58.
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 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 142 of Meeus index or 1095 from Brown series.
Length of current 142 lunation is 29 days, 9 hours and 46 minutes. It is 1 hour and 22 minutes longer than next lunation 143 length.
Length of current synodic month is 2 hours and 58 minutes shorter than the mean length of synodic month, but it is still 3 hours and 11 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠283.1°. At the beginning of next synodic month true anomaly will be ∠312.1°. 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°).
12 days after point of perigee on 7 July 2011 at 14:04 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 21 July 2011 at 22:46 in ♈ Aries.
Moon is 404 622 km (251 420 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 358 km (251 256 mi).
7 days after its ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 27 July 2011 at 12:03 in ♊ Gemini.
7 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
7 days after previous South standstill on 12 July 2011 at 16:51 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.383°. Next 6 days the lunar orbit moves northward to face North declination of ∠23.333° in the next northern standstill on 27 July 2011 at 03:02 in ♊ Gemini.
After 10 days on 30 July 2011 at 18:40 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
