Quarter ♏ Scorpio
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♎ Libra.
* The exact date and time of this First Quarter phase is on 18 July 2010 at 10:11 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1930" and ∠1888".
Next Full Moon is the Buck Moon of July 2010 after 7 days on 26 July 2010 at 01:37.
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 130 of Meeus index or 1083 from Brown series.
Length of current 130 lunation is 29 days, 7 hours and 28 minutes. It is 6 minutes longer than next lunation 131 length.
Length of current synodic month is 5 hours and 16 minutes shorter than the mean length of synodic month, but it is still 53 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠332.7°. At the beginning of next synodic month true anomaly will be ∠349.5°. 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 13 July 2010 at 11:21 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 28 July 2010 at 23:50 in ♓ Pisces.
Moon is 371 330 km (230 734 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 405 955 km (252 249 mi).
7 days after its descending node on 11 July 2010 at 07:30 in ♋ Cancer, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 24 July 2010 at 07:59 in ♑ Capricorn.
21 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 9 July 2010 at 16:50 in ♊ Gemini, when Moon has reached northern declination of ∠25.043°. Next 3 days the lunar orbit moves southward to face South declination of ∠-25.034° in the next southern standstill on 22 July 2010 at 11:12 in ♐ Sagittarius.
After 7 days on 26 July 2010 at 01:37 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
