Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and getting smaller. The 21 days old Moon is in ♉ Taurus.
* The exact date and time of this Last Quarter phase is on 13 August 2009 at 18:55 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠17° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1910" and ∠1894".
Next Full Moon is the Harvest Moon of September 2009 after 22 days on 4 September 2009 at 16:03.
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 118 of Meeus index or 1071 from Brown series.
Length of current 118 lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 minutes shorter than next lunation 119 length.
Length of current synodic month is 5 hours and 17 minutes shorter than the mean length of synodic month, but it is still 52 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠4.5°. At beginning of next synodic month true anomaly will be ∠20.3°. 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 4 August 2009 at 00:42 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.
Moon is 375 238 km (233 162 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 359 642 km (223 471 mi).
8 days after its ascending node on 4 August 2009 at 21:42 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 18 August 2009 at 14:06 in ♋ Cancer.
8 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
11 days after previous South standstill on 1 August 2009 at 13:28 in ♐ Sagittarius, when Moon has reached southern declination of ∠-26.478°. Next 2 days the lunar orbit moves northward to face North declination of ∠26.442° in the next northern standstill on 15 August 2009 at 21:54 in ♊ Gemini.
After 6 days on 20 August 2009 at 10:01 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
