First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 54% and growing larger. The 8 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 13 August 2005 at 02:39 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1896" and ∠1894".
Next Full Moon is the Sturgeon Moon of August 2005 after 6 days on 19 August 2005 at 17:53.
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 69 of Meeus index or 1022 from Brown series.
Length of current 69 lunation is 29 days, 15 hours and 41 minutes. It is 1 minute shorter than next lunation 70 length.
Length of current synodic month is 2 hours and 57 minutes longer than the mean length of synodic month, but it is still 4 hours and 6 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠181.9°. At the beginning of next synodic month true anomaly will be ∠205.9°. 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°).
8 days after point of apogee on 4 August 2005 at 21:49 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 19 August 2005 at 05:32 in ♒ Aquarius.
Moon is 378 065 km (234 919 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 357 396 km (222 076 mi).
3 days after its descending node on 10 August 2005 at 07:53 in ♎ Libra, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 22 August 2005 at 23:05 in ♈ Aries.
17 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the second to the final part of it.
11 days after previous North standstill on 1 August 2005 at 18:06 in ♊ Gemini, when Moon has reached northern declination of ∠28.311°. Next 2 days the lunar orbit moves southward to face South declination of ∠-28.409° in the next southern standstill on 16 August 2005 at 03:16 in ♑ Capricorn.
After 6 days on 19 August 2005 at 17:53 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
