Gibbous ♐ Sagittarius
Moon phase on 17 May 2011 Tuesday is Full Moon, 15 days old Moon is in Scorpio.Share this page: twitter facebook linkedin
Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1936" and ∠1897".
The Full Moon this days is the Flower of May 2011.
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
The Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.
Length of current 140 lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than next lunation 141 length.
Length of current synodic month is 1 hour and 28 minutes longer than the mean length of synodic month, but it is still 5 hours and 35 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠216.7°. At the beginning of next synodic month true anomaly will be ∠248.4°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
2 days after point of perigee on 15 May 2011 at 11:18 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.
Moon is 370 177 km (230 017 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 405 006 km (251 659 mi).
10 days after its descending node on 6 May 2011 at 14:54 in ♊ Gemini, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius.
25 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
11 days after previous North standstill on 6 May 2011 at 03:54 in ♊ Gemini, when Moon has reached northern declination of ∠23.421°. Next day the lunar orbit moves southward to face South declination of ∠-23.403° in the next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
