Quarter ♏ Scorpio
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and growing larger. The 7 days young Moon is in ♎ Libra.
* The exact date and time of this First Quarter phase is on 8 July 2011 at 06:29 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠19° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 4.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1887".
Next Full Moon is the Buck Moon of July 2011 after 6 days on 15 July 2011 at 06:40.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first 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°).
1 day 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 13 days, until it get to the point of next apogee on 21 July 2011 at 22:46 in ♈ Aries.
Moon is 363 442 km (225 832 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 358 km (251 256 mi).
8 days after its descending node on 30 June 2011 at 04:14 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius.
22 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 29 June 2011 at 17:46 in ♊ Gemini, when Moon has reached northern declination of ∠23.399°. Next 4 days the lunar orbit moves southward to face South declination of ∠-23.383° in the next southern standstill on 12 July 2011 at 16:51 in ♐ Sagittarius.
After 6 days 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.
