Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 97% and getting smaller.
Previous main lunar phase is the Full Moon before 1 day on 25 May 2013 at 04:25.
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.
Lunar disc appears visually 4.08% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1894".
Next Full Moon is the Strawberry Moon of June after 27 days on 23 June 2013 at 11:32.
Moon is passing about ∠23° of Sagittarius tropical zodiac sector.
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.
Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 165 of Meeus index or 1118 from Brown series.
Length of current 165 lunation is 29 days, 15 hours and 28 minutes. It is 10 minutes longer than next lunation 166. This is the longest synodic month of 2013.
Length of current synodic month is 2 hours and 44 minutes longer than the mean length of synodic month, but it is still 4 hours and 19 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠143.3°. At the beginning of next synodic month true anomaly is ∠168.8°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon reaches point of perigee at 21:40 on this date, 12 days after apogee on 26 May 2013 at 01:45. Lunar orbit starts getting wider, while the Moon moves outward the Earth 14 days ahead until next apogee on 9 June 2013 at 21:40.
This perigee Moon is 358 375 km (222 684 mi) away from Earth. It is 4 133 km closer than mean perigee distance, but it is still 11 981 km farther than the closest for 21st century.
2 days after its ascending node on 24 May 2013 at 00:40, the Moon follows the northern part of its orbit for the next 10 days untill it crosses the ecliptic from North to South in descending node on 6 June 2013 at 00:59.
2 days after its beginning, the Moon is moving from the beginning to the first part of current draconic month.
At 04:47 on this date Moon meets its South standstill point and reaches southern declination of ∠-20.182°. Next 13 days lunar orbit moves northward in opposite direction to face North declination of ∠20.200° in its northern standstill point on 8 June 2013 at 19:16.
After 13 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 8 June 2013 at 15:56.
