Last Quarter on . The illuminated surface of the moon is 48% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 17 May 2009 at 07:26 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 leaving the last ∠1° of ♒ Aquarius tropical zodiac sector and will enter ♓ Pisces later.
Next Full Moon is the Strawberry Moon of June 2009 after 21 days on 7 June 2009 at 18:12.
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 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1897".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 115 of Meeus index or 1068 from Brown series.
The length of this lunation is 29 days, 8 hours and 48 minutes and it is 1 hour and 24 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 56 minutes shorter than the mean synodic month length. It is 2 hours and 13 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 ∠311.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠332.7°.
3 days since point of apogee on 14 May 2009 at 02:57 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 26 May 2009 at 03:44 in ♊ Gemini.
The Moon is 399 091 km (247 984 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 361 155 km (224 411 mi).
2 days after ascending node on 15 May 2009 at 07:13 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 28 May 2009 at 10:19 in ♌ Leo.
5 days since the last southern standstill on 11 May 2009 at 20:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.486° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠26.451° at the point of next northern standstill on 25 May 2009 at 16:56 in ♊ Gemini.
2 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 24 May 2009 at 12:11 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.
