Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 57% and getting smaller. The 21 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 1 October 2010 at 03:52 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1903" and ∠1916".
Next Full Moon is the Hunter Moon of October 2010 after 22 days on 23 October 2010 at 01:36.
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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.
Length of current 132 lunation is 29 days, 8 hours and 15 minutes. It is 1 hour and 52 minutes shorter than next lunation 133 length.
Length of current synodic month is 4 hours and 29 minutes shorter than the mean length of synodic month, but it is still 1 hour and 40 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠4.6°. At beginning of next synodic month true anomaly will be ∠20.4°. 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°).
9 days after point of apogee on 21 September 2010 at 08:03 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 6 October 2010 at 13:41 in ♍ Virgo.
Moon is 376 592 km (234 003 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 359 453 km (223 354 mi).
13 days after its ascending node on 16 September 2010 at 13:56 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 1 October 2010 at 02:42 in ♋ Cancer.
13 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the first to the middle part of it.
1 day after previous North standstill on 29 September 2010 at 17:37 in ♊ Gemini, when Moon has reached northern declination of ∠24.555°. Next 11 days the lunar orbit moves southward to face South declination of ∠-24.457° in the next southern standstill on 12 October 2010 at 07:49 in ♐ Sagittarius.
After 7 days on 7 October 2010 at 18:44 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
