Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♏ Scorpio

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

Upcoming main Moon phases

Sturgeon Moon after 5 days

Next Full Moon is the Sturgeon Moon of August after 5 days on 2 August 2012 at 03:27.

Apparent angular diameter ∠1973"

Lunar disc appears visually 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1890".

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 155 / 1108

Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 155 of Meeus index or 1108 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.48 days

Length of current 155 lunation is 29 days, 11 hours and 30 minutes. It is 1 hour and 14 minutes longer than next lunation 156.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 14 minutes shorter than the mean length of synodic month, but it is still 4 hours and 55 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠248.7°

This lunation true anomaly is ∠248.7°. At the beginning of next synodic month true anomaly is ∠283.7°. 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

13 days after point of apogee on 13 July 2012 at 16:47, 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 29 July 2012 at 08:30.

Distance to Moon 363 360 km

Moon is 363 360 km (225 781 mi) away from Earth on this date. At previous apogee point before 13 days, distance is 404 783 km (251 520 mi). Moon moves closer next 1 day until perigee, when Earth-Moon distance reaches 367 318 km (228 241 mi).

Moon before ascending node

12 days after its descending node on 14 July 2012 at 20:55, the Moon follows the southern part of its orbit for the next 1 day untill it crosses the ecliptic from South to North in ascending node on 28 July 2012 at 10:34.

Draconic month

26 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

11 days after previous North standstill on 16 July 2012 at 01:18, when Moon reaches northern declination of ∠21.665°, lunar orbit moves southward for the next 2 days to face South declination of ∠-21.592° in the next southern standstill on 29 July 2012 at 12:11.

Syzygy in 5 days

After 5 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 2 August 2012 at 03:27.
