Gibbous ♑ Capricorn
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 60% and growing larger. The 8 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 21 September 2004 at 15:54 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠11° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1912".
Next Full Moon is the Harvest Moon of September 2004 after 6 days on 28 September 2004 at 13:09.
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 58 of Meeus index or 1011 from Brown series.
Length of current 58 lunation is 29 days, 12 hours and 19 minutes. It is 40 minutes longer than next lunation 59 length.
Length of current synodic month is 25 minutes shorter than the mean length of synodic month, but it is still 5 hours and 44 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠269.4°. At the beginning of next synodic month true anomaly will be ∠302.8°. 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°).
Moon is reaching point of perigee on this date at 21:12, this is 14 days after last apogee on 8 September 2004 at 02:42 in ♋ Cancer. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 13 days ahead, until it will get to the point of next apogee on 5 October 2004 at 22:10 in ♋ Cancer.
This perigee Moon is 369 600 km (229 659 mi) away from Earth. This is the year's farthest perigee of 2004. It is 7 092 km closer than the mean perigee distance, but it is still 756 km farther than the closest perigee of 21st century.
4 days after its descending node on 17 September 2004 at 14:51 in ♎ Libra, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 30 September 2004 at 13:30 in ♈ Aries.
19 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
At 02:36 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-27.958°. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.020° in its northern standstill point on 5 October 2004 at 17:37 in ♊ Gemini.
After 6 days on 28 September 2004 at 13:09 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
