First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 55% and growing larger.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 3.18% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1870" and ∠1930".
Next Full Moon is the Worm Moon of March after 6 days on 19 March 2011 at 18:10.
Moon is leaving the last ∠2° of Gemini tropical zodiac sector and enters Cancer later.
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.
Moon is 8 days young. Earth's natural satellite is moving through the first 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 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 is ∠190.9°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).
7 days after point of apogee on 6 March 2011 at 07:50, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 6 days until it gets to the point of perigee on 19 March 2011 at 19:09.
Moon is 383 334 km (238 193 mi) away from Earth on this date. At previous apogee point before 7 days, distance is 406 584 km (252 640 mi). Moon moves closer next 6 days until perigee, when Earth-Moon distance reaches 356 578 km (221 567 mi).
Moon is in descending node at 11:55 on this date, it crosses the ecliptic from South to North. Moon follows the southern part of its orbit for the next 12 days to meet ascending node on 25 March 2011 at 21:09.
14 days after its beginning, the Moon is moving through the middle part of current draconic month.
1 day after previous North standstill on 12 March 2011 at 17:06, when Moon reaches northern declination of ∠23.825°, lunar orbit moves southward for the next 11 days to face South declination of ∠-23.716° in the next southern standstill on 25 March 2011 at 05:02.
After 6 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 19 March 2011 at 18:10.
