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 is entering ♍ Virgo

Moon is passing first ∠2° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1773"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1894".

Strawberry Moon after 8 days

Next Full Moon is the Strawberry Moon of June 2015 after 8 days on 2 June 2015 at 16:19.

Upcoming main Moon phases

  • Full Moon in Sagittarius ♐ on 2 June 2015 at 16:19
  • Last Quarter in Pisces ♓ on 9 June 2015 at 15:42
  • New Moon in Gemini ♊ on 16 June 2015 at 14:05

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 190 / 1143

The Moon is 7 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.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 52 minutes. It is 1 hour and 27 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 52 minutes shorter than the mean synodic month length. It is 3 hours and 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠48.8°

At the beginning of the lunation cycle the true anomaly is ∠48.8°. At the beginning of next synodic month the true anomaly is going to be ∠78.1°.

Moon before perigee

10 days after point of perigee on 15 May 2015 at 00:23 in ♈ Aries. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 26 May 2015 at 22:12 in ♍ Virgo.

Distance to Moon 404 294 km

The Moon is 404 294 km (251 217 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 246 km (251 187 mi).

Moon before ascending node

10 days after descending node on 14 May 2015 at 20:37 in ♈ Aries. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 28 May 2015 at 14:40 in ♎ Libra.

Draconic month

24 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

5 days since the previous standstill on 20 May 2015 at 09:41 in ♊ Gemini when the Moon has reached North declination of ∠18.389°, the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-18.440° at the point of next southern standstill on 3 June 2015 at 21:10 in ♐ Sagittarius.

Syzygy in 8 days

In 8 days on 2 June 2015 at 16:19 in ♐ Sagittarius the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
