First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 47% and growing larger. The 7 days young Moon is in ♐ Sagittarius.
* The exact date and time of this First Quarter phase is on 13 September 2002 at 18:08 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠17° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1907".
Next Full Moon is the Harvest Moon of September 2002 after 8 days on 21 September 2002 at 13:59.
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 33 of Meeus index or 986 from Brown series.
Length of current 33 lunation is 29 days, 8 hours and 7 minutes. It is 1 hour and 10 minutes shorter than next lunation 34 length.
Length of current synodic month is 4 hours and 37 minutes shorter than the mean length of synodic month, but it is still 1 hour and 32 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠343.1°. At the beginning of next synodic month true anomaly will be ∠358.6°. 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°).
5 days after point of perigee on 8 September 2002 at 03:14 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 23 September 2002 at 03:26 in ♈ Aries.
Moon is 374 295 km (232 576 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 406 351 km (252 495 mi).
Moon is in descending node in ♐ Sagittarius at 03:39 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 14 days to meet ascending node on 27 September 2002 at 16:06 in ♊ Gemini.
12 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the middle to the last part of it.
10 days after previous North standstill on 2 September 2002 at 16:03 in ♋ Cancer, when Moon has reached northern declination of ∠25.282°. Next day the lunar orbit moves southward to face South declination of ∠-25.377° in the next southern standstill on 15 September 2002 at 05:34 in ♑ Capricorn.
After 8 days on 21 September 2002 at 13:59 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
