Previous main lunar phase is the Full Moon before 4 days on 27 March 2013 at 09:27.
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.
Moon is passing about ∠5° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1920".
Next Full Moon is the Pink Moon of April 2013 after 25 days on 25 April 2013 at 19:57.
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.
The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 163 of Meeus index or 1116 from Brown series.
Length of current 163 lunation is 29 days, 13 hours and 44 minutes. It is 1 hour and 9 minutes shorter than next lunation 164 length.
Length of current synodic month is 1 hour longer than the mean length of synodic month, but it is still 6 hours and 3 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠73.6°. At beginning of next synodic month true anomaly will be ∠110.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon is reaching point of perigee on this date at 03:55, this is 12 days after last apogee on 19 March 2013 at 03:13 in ♊ Gemini. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 15 days ahead, until it will get to the point of next apogee on 15 April 2013 at 22:21 in ♊ Gemini.
This perigee Moon is 367 494 km (228 350 mi) away from Earth. It is 4 986 km closer than the mean perigee distance, but it is still 2 862 km farther than the closest perigee of 21st century.
1 day after its ascending node on 30 March 2013 at 05:55 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 12 April 2013 at 12:12 in ♉ Taurus.
1 day after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
12 days after previous North standstill on 18 March 2013 at 21:50 in ♊ Gemini, when Moon has reached northern declination of ∠20.335°. Next day the lunar orbit moves southward to face South declination of ∠-20.250° in the next southern standstill on 1 April 2013 at 12:03 in ♐ Sagittarius.
After 9 days on 10 April 2013 at 09:35 in ♈ Aries, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
