Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon is passing about ∠10° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 2.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1927".
The Full Moon this days is the Worm of March 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 138 of Meeus index or 1091 from Brown series.
Length of current 138 lunation is 29 days, 17 hours and 46 minutes. It is 1 hour and 28 minutes longer than next lunation 139 length.
Length of current synodic month is 5 hours and 2 minutes longer than the mean length of synodic month, but it is still 2 hours and 1 minute shorter, compared to 21st century longest.
This lunation true anomaly is ∠167°. At the beginning of next synodic month true anomaly will be ∠190.9°. 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°).
1 day after point of perigee on 19 March 2011 at 19:09 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 2 April 2011 at 09:00 in ♓ Pisces.
Moon is 363 574 km (225 914 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 406 656 km (252 684 mi).
7 days after its descending node on 13 March 2011 at 11:55 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 25 March 2011 at 21:09 in ♐ Sagittarius.
21 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
7 days after previous North standstill on 12 March 2011 at 17:06 in ♊ Gemini, when Moon has reached northern declination of ∠23.825°. Next 4 days the lunar orbit moves southward to face South declination of ∠-23.716° in the next southern standstill on 25 March 2011 at 05:02 in ♐ Sagittarius.
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
