Quarter ♏ Scorpio
Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 54% and getting smaller. The 21 days old Moon is in ♏ Scorpio.
* The exact date and time of this Last Quarter phase is on 31 January 2081 at 20:37 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠8° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 2.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1897" and ∠1947".
Next Full Moon is the Snow Moon of February 2081 after 23 days on 23 February 2081 at 14:27.
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 1002 of Meeus index or 1955 from Brown series.
Length of current 1002 lunation is 29 days, 19 hours and 15 minutes. This is the year's longest synodic month of 2081. It is 15 minutes longer than next lunation 1003 length.
Length of current synodic month is 6 hours and 31 minutes longer than the mean length of synodic month, but it is still 32 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠151.7°. At beginning of next synodic month true anomaly will be ∠177.5°. 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°).
5 days after point of perigee on 25 January 2081 at 17:17 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 8 days, until it get to the point of next apogee on 9 February 2081 at 03:24 in ♒ Aquarius.
Moon is 377 751 km (234 724 mi) away from Earth on this date. Moon moves farther next 8 days until apogee, when Earth-Moon distance will reach 406 582 km (252 638 mi).
3 days after its descending node on 28 January 2081 at 10:41 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 11 February 2081 at 16:49 in ♓ Pisces.
15 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 22 January 2081 at 17:53 in ♊ Gemini, when Moon has reached northern declination of ∠28.501°. Next 4 days the lunar orbit moves southward to face South declination of ∠-28.557° in the next southern standstill on 4 February 2081 at 13:10 in ♐ Sagittarius.
After 8 days on 8 February 2081 at 20:17 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
