Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon is passing about ∠21° of ♓ Pisces tropical zodiac sector.
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1780" and ∠1907".
The Full Moon this days is the Harvest of September 2011.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
The Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.
Length of current 144 lunation is 29 days, 8 hours and 5 minutes. This is the year's shortest synodic month of 2011. It is 42 minutes shorter than next lunation 145 length.
Length of current synodic month is 4 hours and 39 minutes shorter than the mean length of synodic month, but it is still 1 hour and 30 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠333.4°. At the beginning of next synodic month true anomaly will be ∠350.1°. 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 30 August 2011 at 17:35 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 15 September 2011 at 06:23 in ♈ Aries.
Moon is 402 728 km (250 244 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 406 068 km (252 319 mi).
7 days after its ascending node on 5 September 2011 at 07:36 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 19 September 2011 at 19:38 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 5 September 2011 at 05:01 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.047°. Next 7 days the lunar orbit moves northward to face North declination of ∠22.890° in the next northern standstill on 19 September 2011 at 20:05 in ♊ Gemini.
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
