Waning Gibbous on . The illuminated surface of the moon is 90% and getting smaller. The lunar cycle is 17 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 25 April 2013 at 19:57.
Next Full Moon is the Flower Moon of May 2013 after 26 days on 25 May 2013 at 04:25.
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 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1905".
The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 164 of Meeus index or 1117 from Brown series.
The length of this lunation is 29 days, 14 hours and 53 minutes and it is 35 minutes 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 2 hours and 9 minutes longer than the mean synodic month length. It is 4 hours and 54 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 ∠110.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠143.3°.
1 day since point of perigee on 27 April 2013 at 19:48 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 15 days until the Moon reaches the point of next apogee on 13 May 2013 at 13:31 in ♊ Gemini.
The Moon is 363 653 km (225 963 mi) away from Earth and getting further over the next 15 days until the point apogee when Earth-Moon distance is going to be 405 827 km (252 169 mi).
1 day after ascending node on 26 April 2013 at 14:07 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 9 May 2013 at 19:12 in ♉ Taurus.
At 19:05 the Moon is meeting its standstill point to reach South declination of ∠-20.170°. Over the upcoming 14 days the lunar orbit is going to tilt northward to face maximum declination of ∠20.170° at the point of next northern standstill in ♊ Gemini on 12 May 2013 at 12:30.
1 day since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 11 days on 10 May 2013 at 00:29 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.
