Yesterday | Tomorrow

Moonrise and moonset

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

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.88% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1894".

Strawberry Moon after 6 days

Next Full Moon is the Strawberry Moon of June after 6 days on 2 June 2015 at 16:19.

Moon in Virgo

Moon is passing about ∠21° of Virgo tropical zodiac sector.

Upcoming Moon phases

Lunar orbit details for

Neap tide

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

Lunation 190 / 1143

Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 190 of Meeus index or 1143 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.41 days

Length of current 190 lunation is 29 days, 9 hours and 52 minutes. It is 1 hour and 27 minutes shorter than next lunation 191.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 52 minutes shorter than the mean length of synodic month, but it is still 3 hours and 17 minutes longer, compared to 21st century shortest.

True anomaly ∠48.8°

This lunation true anomaly is ∠48.8°. At the beginning of next synodic month true anomaly is ∠78.1°. 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 after apogee

1 day after point of apogee on 26 May 2015 at 22:12, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 14 days until it gets to the point of perigee on 10 June 2015 at 04:39.

Distance to Moon 405 501 km

Moon is 405 501 km (251 966 mi) away from Earth on this date. At previous apogee point before 1 day, distance is 404 246 km (251 187 mi). Moon moves closer next 14 days until perigee, when Earth-Moon distance reaches 369 713 km (229 729 mi).

Moon before ascending node

12 days after its descending node on 14 May 2015 at 20:37, 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 May 2015 at 14:40.

Draconic month

25 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 after northern standstill

6 days after previous North standstill on 20 May 2015 at 09:41, when Moon reaches northern declination of ∠18.389°, lunar orbit moves southward for the next 7 days to face South declination of ∠-18.440° in the next southern standstill on 3 June 2015 at 21:10.

Syzygy in 6 days

After 6 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 2 June 2015 at 16:19.
