Waning Gibbous on . The illuminated surface of the moon is 88% and getting smaller. The lunar cycle is 18 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 leaving the last ∠3° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.
Previous main lunar phase is the Full Moon before 3 days on 4 May 2015 at 03:42.
Next Full Moon is the Strawberry Moon of June 2015 after 26 days on 2 June 2015 at 16:19.
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 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1885" and ∠1901".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 189 of Meeus index or 1142 from Brown series.
The length of this lunation is 29 days, 9 hours and 16 minutes and it is 36 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2015. 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 3 hours and 28 minutes shorter than the mean synodic month length. It is 2 hours and 41 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 ∠27.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠48.8°.
8 days since point of apogee on 29 April 2015 at 03:55 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 15 May 2015 at 00:23 in ♈ Aries.
The Moon is 380 347 km (236 337 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 366 024 km (227 437 mi).
6 days after ascending node on 1 May 2015 at 09:50 in ♎ Libra the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 14 May 2015 at 20:37 in ♈ Aries.
At 13:39 the Moon is meeting its standstill point to reach South declination of ∠-18.343°. Over the upcoming 12 days the lunar orbit is going to tilt northward to face maximum declination of ∠18.389° at the point of next northern standstill in ♊ Gemini on 20 May 2015 at 09:41.
6 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.
In 10 days on 18 May 2015 at 04:13 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.
