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 ♏ Scorpio.
* The exact date and time of this Last Quarter phase is on 18 February 2017 at 19:33 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 9.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1941".
Next Full Moon is the Worm Moon of March 2017 after 22 days on 12 March 2017 at 14:54.
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 211 of Meeus index or 1164 from Brown series.
Length of current 211 lunation is 29 days, 14 hours and 51 minutes. It is 2 hours and 52 minutes longer than next lunation 212 length.
Length of current synodic month is 2 hours and 7 minutes longer than the mean length of synodic month, but it is still 4 hours and 56 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠259.5°. At the beginning of next synodic month true anomaly will be ∠295°. 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 apogee on this date at 21:14, this is 12 days after last perigee on 6 February 2017 at 13:59 in ♊ Gemini. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 3 March 2017 at 07:24 in ♉ Taurus.
This apogee Moon is 404 376 km (251 268 mi) away from Earth. It is 1 032 km farther than the mean apogee distance, but it is still 2 333 km closer than the farthest apogee of 21st century.
6 days after its ascending node on 11 February 2017 at 19:49 in ♌ Leo, the Moon is following the northern part of its orbit for the next 7 days, until it will cross the ecliptic from North to South in descending node on 26 February 2017 at 06:28 in ♓ Pisces.
6 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
10 days after previous North standstill on 7 February 2017 at 18:34 in ♊ Gemini, when Moon has reached northern declination of ∠18.865°. Next 3 days the lunar orbit moves southward to face South declination of ∠-18.848° in the next southern standstill on 21 February 2017 at 20:50 in ♑ Capricorn.
After 8 days on 26 February 2017 at 14:58 in ♓ Pisces, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
