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 ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 4 October 2011 at 03:15 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠15° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1881" and ∠1918".
Next Full Moon is the Hunter Moon of October 2011 after 7 days on 12 October 2011 at 02:06.
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 145 of Meeus index or 1098 from Brown series.
Length of current 145 lunation is 29 days, 8 hours and 47 minutes. It is 1 hour and 27 minutes shorter than next lunation 146 length.
Length of current synodic month is 3 hours and 57 minutes shorter than the mean length of synodic month, but it is still 2 hours and 12 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠350.1°. At beginning of next synodic month true anomaly will be ∠5.3°. 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°).
6 days after point of perigee on 28 September 2011 at 01:01 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 12 October 2011 at 11:43 in ♈ Aries.
Moon is 381 057 km (236 778 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 406 435 km (252 547 mi).
2 days after its ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 16 October 2011 at 21:01 in ♊ Gemini.
2 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
2 days after previous South standstill on 2 October 2011 at 11:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-22.791°. Next 12 days the lunar orbit moves northward to face North declination of ∠22.665° in the next northern standstill on 17 October 2011 at 02:06 in ♊ Gemini.
After 7 days on 12 October 2011 at 02:06 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
