First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 45% and growing larger. The 7 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 20 October 2004 at 21:59 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠22° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1928".
Next Full Moon is the Hunter Moon of October 2004 after 7 days on 28 October 2004 at 03:07.
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 59 of Meeus index or 1012 from Brown series.
Length of current 59 lunation is 29 days, 11 hours and 39 minutes. It is 37 minutes longer than next lunation 60 length.
Length of current synodic month is 1 hour and 5 minutes shorter than the mean length of synodic month, but it is still 5 hours and 4 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠302.8°. At the beginning of next synodic month true anomaly will be ∠327.5°. 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°).
2 days after point of perigee on 18 October 2004 at 00:03 in ♐ Sagittarius. 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 2 November 2004 at 18:09 in ♋ Cancer.
Moon is 363 811 km (226 062 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 999 km (251 655 mi).
5 days after its descending node on 14 October 2004 at 21:47 in ♎ Libra, 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 27 October 2004 at 21:41 in ♈ Aries.
19 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the second to the final part of it.
1 day after previous South standstill on 19 October 2004 at 08:00 in ♑ Capricorn, when Moon has reached southern declination of ∠-28.048°. Next 12 days the lunar orbit moves northward to face North declination of ∠28.042° in the next northern standstill on 2 November 2004 at 01:32 in ♋ Cancer.
After 7 days on 28 October 2004 at 03:07 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
