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 ♈ Aries.
* The exact date and time of this Last Quarter phase is on 13 July 2001 at 18:45 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠18° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 4.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1807" and ∠1888".
Next Full Moon is the Sturgeon Moon of August 2001 after 21 days on 4 August 2001 at 05:56.
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 18 of Meeus index or 971 from Brown series.
Length of current 18 lunation is 29 days, 7 hours and 47 minutes. It is 36 minutes longer than next lunation 19 length.
Length of current synodic month is 4 hours and 57 minutes shorter than the mean length of synodic month, but it is still 1 hour and 12 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠324.1°. At the beginning of next synodic month true anomaly will be ∠342.5°. 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°).
4 days after point of apogee on 9 July 2001 at 11:24 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 21 July 2001 at 20:44 in ♌ Leo.
Moon is 396 628 km (246 453 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 359 027 km (223 089 mi).
8 days after its descending node on 5 July 2001 at 00:48 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 19 July 2001 at 08:24 in ♋ Cancer.
21 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
7 days after previous South standstill on 5 July 2001 at 12:19 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.413°. Next 6 days the lunar orbit moves northward to face North declination of ∠23.418° in the next northern standstill on 19 July 2001 at 17:53 in ♋ Cancer.
After 7 days on 20 July 2001 at 19:44 in ♋ Cancer, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
