First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 49% and growing larger.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 3.85% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1898".
Next Full Moon is the Sturgeon Moon of August after 7 days on 31 August 2012 at 13:58.
Moon is passing first ∠1° of Sagittarius tropical zodiac sector.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 156 of Meeus index or 1109 from Brown series.
Length of current 156 lunation is 29 days, 10 hours and 16 minutes. It is 24 minutes longer than next lunation 157.
Length of current synodic month is 2 hours and 28 minutes shorter than the mean length of synodic month, but it is still 3 hours and 41 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠283.7°. At the beginning of next synodic month true anomaly is ∠312.9°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).
1 day after point of perigee on 23 August 2012 at 19:39, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 13 days until it gets to the point of apogee on 7 September 2012 at 06:00.
Moon is 363 323 km (225 759 mi) away from Earth on this date. At previous perigee point before 1 day, distance is 369 731 km (229 740 mi). Moon moves farther next 13 days until apogee, when Earth-Moon distance reaches 404 296 km (251 218 mi).
Moon is in ascending node at 11:38 on this date, it crosses the ecliptic from North to South. Moon follows the northern part of its orbit for the next 13 days to meet descending node on 7 September 2012 at 02:08.
At 11:38 on this date Moon completes the old and enters a new draconic month.
12 days after previous North standstill on 12 August 2012 at 09:47, when Moon reaches northern declination of ∠21.492°, lunar orbit moves southward for the next 1 day to face South declination of ∠-21.379° in the next southern standstill on 25 August 2012 at 18:40.
After 7 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 31 August 2012 at 13:58.
