Moon phase and lunation

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 6 August 2013 at 21:51.

Sturgeon Moon after 9 days

Next Full Moon is the Sturgeon Moon of August after 9 days on 21 August 2013 at 01:45.

Moon in Libra

Moon is passing about ∠12° of Libra tropical zodiac sector.

Upcoming Moon phases

Apparent angular diameter ∠1879"

Lunar disc appears visually 0.77% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1879" and ∠1893".

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 168 / 1121

Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.57 days

Length of current 168 lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than next lunation 169.

Lunation length longer than mean

Length of current synodic month is 1 hour and 1 minute longer than the mean length of synodic month, but it is still 6 hours and 2 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠216.9°

This lunation true anomaly is ∠216.9°. At the beginning of next synodic month true anomaly is ∠249.2°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon before perigee

8 days after point of apogee on 3 August 2013 at 08:53, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 7 days until it gets to the point of perigee on 19 August 2013 at 01:26.

Distance to Moon 381 482 km

Moon is 381 482 km (237 042 mi) away from Earth on this date. At previous apogee point before 8 days, distance is 405 834 km (252 174 mi). Moon moves closer next 7 days until perigee, when Earth-Moon distance reaches 362 265 km (225 101 mi).

Moon before ascending node

12 days after its descending node on 30 July 2013 at 05:50, the Moon follows the southern part of its orbit for the next 2 days untill it crosses the ecliptic from South to North in ascending node on 13 August 2013 at 16:20.

Draconic month

24 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon before southern standstill

9 days after previous North standstill on 2 August 2013 at 09:24, when Moon reaches northern declination of ∠20.025°, lunar orbit moves southward for the next 5 days to face South declination of ∠-19.906° in the next southern standstill on 16 August 2013 at 12:06.

Syzygy in 9 days

After 9 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 21 August 2013 at 01:45.
