Moon phase and lunation

Moonrise and moonset

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.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 27 March 2013 at 09:27.

Worm Moon before 3 days

Next Full Moon is the Pink Moon of April after 26 days on 25 April 2013 at 19:57.

Moon in Scorpio

Moon is passing about ∠20° of Scorpio tropical zodiac sector.

Upcoming Moon phases

Apparent angular diameter ∠1957"

Lunar disc appears visually 1.88% wider than solar disc. Moon and Sun apparent angular diameters are ∠1957" and ∠1921".

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 163 / 1116

Moon is 18 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.

Previous | Current lunation | Next

Synodic month length 29.57 days

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.

Lunation length longer than mean

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.

Lunar orbit position on

True anomaly ∠73.6°

This lunation true anomaly is ∠73.6°. At the beginning of next synodic month true anomaly is ∠110.3°. 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 before perigee

11 days after point of apogee on 19 March 2013 at 03:13, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 1 day until it gets to the point of perigee on 31 March 2013 at 03:55.

Distance to Moon 366 215 km

Moon is 366 215 km (227 556 mi) away from Earth on this date. At previous apogee point before 11 days, distance is 404 262 km (251 197 mi). Moon moves closer next 1 day until perigee, when Earth-Moon distance reaches 367 494 km (228 350 mi).

Moon in ascending node

Moon is in ascending node at 05:55 on this date, it crosses the ecliptic from North to South. Moon follows the northern part of its orbit for the next 13 days to meet descending node on 12 April 2013 at 12:12.

New draconic month

At 05:55 on this date Moon completes the old and enters a new draconic month.

Previous | Next

Moon before southern standstill

11 days after previous North standstill on 18 March 2013 at 21:50, when Moon reaches northern declination of ∠20.335°, lunar orbit moves southward for the next 2 days to face South declination of ∠-20.250° in the next southern standstill on 1 April 2013 at 12:03.

Syzygy in 10 days

After 10 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 10 April 2013 at 09:35.
