Last Quarter on . The illuminated surface of the moon is 43% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 10 February 2091 at 21:11 UTC.
The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Main moon phases of the following lunar cycle.
Moon is passing first ∠1° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Worm Moon of March 2091 after 22 days on 5 March 2091 at 15:59.
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.
Lunar disc appears visually 0.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1937" and ∠1944".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1126 of Meeus index or 2079 from Brown series.
The length of this lunation is 29 days, 17 hours and 7 minutes and it is 1 hour shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 4 hours and 23 minutes longer than the mean synodic month length. It is 2 hours and 40 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠102° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠137.9°.
5 days since point of perigee on 6 February 2091 at 09:12 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 22 February 2091 at 08:37 in ♈ Aries.
The Moon is 370 121 km (229 983 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 740 km (252 115 mi).
5 days after ascending node on 5 February 2091 at 23:52 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 19 February 2091 at 08:56 in ♓ Pisces.
10 days since the last northern standstill on 1 February 2091 at 06:49 in ♋ Cancer when the Moon has reached North declination of ∠18.537° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-18.496° at the point of next southern standstill on 14 February 2091 at 00:36 in ♑ Capricorn.
5 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 18 February 2091 at 09:38 in ♒ Aquarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
