Last Quarter on . The illuminated surface of the moon is 50% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 23 April 2003 at 12:18 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 ∠3° of ♒ Aquarius tropical zodiac sector.
Next Full Moon is the Flower Moon of May 2003 after 22 days on 16 May 2003 at 03:36.
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 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1908".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 40 of Meeus index or 993 from Brown series.
The length of this lunation is 29 days, 16 hours and 56 minutes and it is 51 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2003. 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 4 hours and 12 minutes longer than the mean synodic month length. It is 2 hours and 51 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 ∠157.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠181.7°.
6 days since point of perigee on 17 April 2003 at 04:58 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 1 May 2003 at 07:39 in ♉ Taurus.
The Moon is 381 190 km (236 860 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 530 km (252 606 mi).
4 days after descending node on 19 April 2003 at 00:24 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 May 2003 at 02:17 in ♉ Taurus.
1 day since the last southern standstill on 21 April 2003 at 17:59 in ♑ Capricorn when the Moon has reached South declination of ∠-26.442° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠26.496° at the point of next northern standstill on 6 May 2003 at 09:48 in ♋ Cancer.
17 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.
In 8 days on 1 May 2003 at 12:15 in ♉ Taurus 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.
