Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 17 May 2009 at 07:26.

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 ♈ Aries

Moon is passing about ∠7° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1856"

Lunar disc appears visually 2.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1856" and ∠1896".

Strawberry Moon after 18 days

Next Full Moon is the Strawberry Moon of June 2009 after 18 days on 7 June 2009 at 18:12.

Upcoming main Moon phases

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 115 / 1068

The Moon is 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 115 of Meeus index or 1068 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 48 minutes. It is 1 hour and 24 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 shorter than mean

The length of the current synodic month is 3 hours and 56 minutes shorter than the mean synodic month length. It is 2 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠311.7°

At the beginning of the lunation cycle the true anomaly is ∠311.7°. At the beginning of next synodic month the true anomaly is going to be ∠332.7°.

Moon before apogee

6 days after point of apogee on 14 May 2009 at 02:57 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 26 May 2009 at 03:44 in ♊ Gemini.

Previous apogeeNext perigee

Distance to Moon 386 189 km

The Moon is 386 189 km (239 967 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 361 155 km (224 411 mi).

Moon after ascending node

5 days after ascending node on 15 May 2009 at 07:13 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 28 May 2009 at 10:19 in ♌ Leo.

Draconic month

5 days since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

8 days since the previous standstill on 11 May 2009 at 20:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.486°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠26.451° at the point of next northern standstill on 25 May 2009 at 16:56 in ♊ Gemini.

Syzygy in 4 days

In 4 days on 24 May 2009 at 12:11 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.
