Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 17 May 2011 at 11:09.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♐ Sagittarius

Moon is passing about ∠25° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1892"

Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1892" and ∠1896".

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2011 after 27 days on 15 June 2011 at 20:13.

Upcoming main Moon phases

  • Last Quarter in Aquarius ♒ on 24 May 2011 at 18:52
  • 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

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 17 days old. Earth's natural satellite is moving from the middle to the last 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 perigee

4 days after point of perigee on 15 May 2011 at 11:18 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.

Previous perigeeNext apogee

Distance to Moon 378 919 km

The Moon is 378 919 km (235 449 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 006 km (251 659 mi).

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 09:03 crossing the ecliptic from South to North to meet descending node 14 days later on 2 June 2011 at 20:21 in ♊ Gemini.

Previous nodeNext node

New draconic month

At 09:03 the Moon completes the previous draconic month and enters the new one.

Moon after southern standstill

1 day 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 13 days to face maximum declination of ∠23.393° at the point of next northern standstill on 2 June 2011 at 09:54 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 13 days

In 13 days 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.
