Last Quarter on . The illuminated surface of the moon is 54% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 4 June 2010 at 22:13 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 about ∠9° of ♓ Pisces tropical zodiac sector.
Next Full Moon is the Strawberry Moon of June 2010 after 21 days on 26 June 2010 at 11:30.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1891".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 128 of Meeus index or 1081 from Brown series.
The length of this lunation is 29 days, 10 hours and 10 minutes and it is 1 hour and 44 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 2 hours and 34 minutes shorter than the mean synodic month length. It is 3 hours and 35 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠282.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠311.3°.
1 day since point of apogee on 3 June 2010 at 16:50 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 15 June 2010 at 14:54 in ♋ Cancer.
The Moon is 405 048 km (251 685 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 365 937 km (227 383 mi).
4 days after ascending node on 30 May 2010 at 18:07 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 13 June 2010 at 21:54 in ♋ Cancer.
6 days since the last southern standstill on 28 May 2010 at 22:09 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.029° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠25.030° at the point of next northern standstill on 12 June 2010 at 07:06 in ♊ Gemini.
4 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 12 June 2010 at 11:15 in ♊ Gemini 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.
