Last Quarter on . The illuminated surface of the moon is 55% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 23 May 2003 at 00:31 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 ∠25° of ♒ Aquarius tropical zodiac sector.
Next Full Moon is the Strawberry Moon of June 2003 after 22 days on 14 June 2003 at 11:16.
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 2.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1847" and ∠1895".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 41 of Meeus index or 994 from Brown series.
The length of this lunation is 29 days, 16 hours and 5 minutes and it is 1 hour and 46 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 3 hours and 21 minutes longer than the mean synodic month length. It is 3 hours and 42 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 ∠181.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠205.5°.
6 days since point of perigee on 15 May 2003 at 15:39 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 6 days until the Moon reaches the point of next apogee on 28 May 2003 at 13:05 in ♉ Taurus.
The Moon is 388 138 km (241 178 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 171 km (252 383 mi).
6 days after descending node on 16 May 2003 at 10:51 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 May 2003 at 08:33 in ♉ Taurus.
3 days since the last southern standstill on 19 May 2003 at 03:13 in ♑ Capricorn when the Moon has reached South declination of ∠-26.503° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠26.491° at the point of next northern standstill on 2 June 2003 at 15:27 in ♋ Cancer.
19 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 31 May 2003 at 04:20 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.
