Quarter ♌ Leo
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 46% and growing larger. The 7 days young Moon is in ♌ Leo.
* The exact date and time of this First Quarter phase is on 10 May 2011 at 20:33 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠15° of ♌ Leo tropical zodiac sector.
Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1936" and ∠1900".
Next Full Moon is the Flower Moon of May 2011 after 6 days on 17 May 2011 at 11:09.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.
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°).
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.
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°.
10 days after point of apogee on 29 April 2011 at 18:02 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 15 May 2011 at 11:18 in ♎ Libra.
The Moon is 370 290 km (230 088 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 362 133 km (225 019 mi).
3 days after descending node on 6 May 2011 at 14:54 in ♊ Gemini. The Moon is located south of the ecliptic over the following 8 days, until the lunar orbit crosses from South to North in ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius.
18 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.
4 days since the previous standstill on 6 May 2011 at 03:54 in ♊ Gemini when the Moon has reached North declination of ∠23.421°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-23.403° at the point of next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.
In 6 days on 17 May 2011 at 11:09 in ♏ Scorpio 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.
