Moon phase and lunation details

6 days after Last Quarter

Previous main lunar phase is the Last Quarter before 6 days on 24 May 2011 at 18:52.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♉ Taurus

Moon is passing about ∠24° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1799"

Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1799" and ∠1892".

Strawberry Moon after 15 days

Next Full Moon is the Strawberry Moon of June 2011 after 15 days on 15 June 2011 at 20:13.

Upcoming main Moon phases

  • New Moon in Gemini ♊ on 1 June 2011 at 21:03
  • First Quarter in Virgo ♍ on 9 June 2011 at 02:11
  • Full Moon in Sagittarius ♐ on 15 June 2011 at 20:13
  • Last Quarter in Aries ♈ on 23 June 2011 at 11:48

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 140 / 1093

The Moon is 28 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 28 minutes longer than the mean synodic month length. It is 5 hours and 35 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠216.7°

At the beginning of the lunation cycle the true anomaly is ∠216.7°. At the beginning of next synodic month the true anomaly is going to be ∠248.4°.

Moon after apogee

4 days after point of apogee on 27 May 2011 at 09:58 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 12 June 2011 at 01:42 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 398 468 km

The Moon is 398 468 km (247 597 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 367 188 km (228 160 mi).

Moon before descending node

12 days after ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 2 days, until the lunar orbit crosses from North to South in descending node on 2 June 2011 at 20:21 in ♊ Gemini.

Previous nodeNext node

Draconic month

12 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

12 days since the previous standstill on 18 May 2011 at 23:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.403°, the lunar orbit is extending northward over the next day to face maximum declination of ∠23.393° at the point of next northern standstill on 2 June 2011 at 09:54 in ♊ Gemini.

Syzygy in 1 day

In 1 day on 1 June 2011 at 21:03 in ♊ Gemini the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
