First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 55% and growing larger. The 8 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 20 August 2007 at 23:54 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠4° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1781" and ∠1897".
Next Full Moon is the Sturgeon Moon of August 2007 after 6 days on 28 August 2007 at 10:35.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 94 of Meeus index or 1047 from Brown series.
Length of current 94 lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 34 minutes shorter than next lunation 95 length.
Length of current synodic month is 58 minutes longer than the mean length of synodic month, but it is still 6 hours and 5 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠97.3°. At beginning of next synodic month true anomaly will be ∠131.4°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
2 days after point of apogee on 19 August 2007 at 03:28 in ♏ Scorpio. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 31 August 2007 at 00:12 in ♈ Aries.
Moon is 402 403 km (250 042 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 364 174 km (226 287 mi).
7 days after its descending node on 14 August 2007 at 07:25 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 28 August 2007 at 14:27 in ♒ Aquarius.
20 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
12 days after previous North standstill on 8 August 2007 at 23:02 in ♊ Gemini, when Moon has reached northern declination of ∠28.342°. Next day the lunar orbit moves southward to face South declination of ∠-28.377° in the next southern standstill on 23 August 2007 at 08:02 in ♐ Sagittarius.
After 6 days on 28 August 2007 at 10:35 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
