Previous main lunar phase is the First Quarter before 5 days on 8 July 2011 at 06:29.
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.
Lunar disc appears visually 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1894" and ∠1888".
Next Full Moon is the Buck Moon of July 2011 after 1 day on 15 July 2011 at 06:40.
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 13 days young. Earth's natural satellite is moving from the first to the middle 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°).
5 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 8 days, until it get to the point of next apogee on 21 July 2011 at 22:46 in ♈ Aries.
Moon is 378 433 km (235 147 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 404 358 km (251 256 mi).
Moon is in ascending node in ♐ Sagittarius at 02:27 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 14 days to meet descending node on 27 July 2011 at 12:03 in ♊ Gemini.
At 02:27 on this date the Moon is completing its previous draconic month and is entering the new one.
1 day after previous South standstill on 12 July 2011 at 16:51 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.383°. Next 13 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 1 day on 15 July 2011 at 06:40 in ♑ Capricorn, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
