Gibbous ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 58% and growing larger. The 8 days young Moon is in ♈ Aries.
* The exact date and time of this First Quarter phase is on 18 December 2004 at 16:40 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠8° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 3.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1884" and ∠1950".
Next Full Moon is the Cold Moon of December 2004 after 7 days on 26 December 2004 at 15:06.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 61 of Meeus index or 1014 from Brown series.
Length of current 61 lunation is 29 days, 10 hours and 34 minutes. This is the year's shortest synodic month of 2004. It is 9 minutes longer than next lunation 62 length.
Length of current synodic month is 2 hours and 10 minutes shorter than the mean length of synodic month, but it is still 3 hours and 59 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠345.8°. At beginning of next synodic month true anomaly will be ∠1.4°. 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°).
6 days after point of perigee on 12 December 2004 at 21:30 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 27 December 2004 at 19:15 in ♋ Cancer.
Moon is 380 443 km (236 396 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 406 488 km (252 580 mi).
10 days after its descending node on 8 December 2004 at 16:57 in ♎ Libra, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 21 December 2004 at 06:51 in ♉ Taurus.
25 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
6 days after previous South standstill on 13 December 2004 at 00:27 in ♑ Capricorn, when Moon has reached southern declination of ∠-27.935°. Next 7 days the lunar orbit moves northward to face North declination of ∠27.905° in the next northern standstill on 26 December 2004 at 14:10 in ♊ Gemini.
After 7 days on 26 December 2004 at 15:06 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
