First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 57% and growing larger. The 8 days young Moon is in ♋ Cancer.
* The exact date and time of this First Quarter phase is on 19 March 2013 at 17:27 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠8° of ♋ Cancer tropical zodiac sector.
Lunar disc appears visually 8.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1926".
Next Full Moon is the Worm Moon of March 2013 after 6 days on 27 March 2013 at 09:27.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 163 of Meeus index or 1116 from Brown series.
Length of current 163 lunation is 29 days, 13 hours and 44 minutes. It is 1 hour and 9 minutes shorter than next lunation 164 length.
Length of current synodic month is 1 hour longer than the mean length of synodic month, but it is still 6 hours and 3 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠73.6°. At beginning of next synodic month true anomaly will be ∠110.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
1 day after point of apogee on 19 March 2013 at 03:13 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 31 March 2013 at 03:55 in ♐ Sagittarius.
Moon is 404 464 km (251 322 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 367 494 km (228 350 mi).
4 days after its descending node on 16 March 2013 at 06:15 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 30 March 2013 at 05:55 in ♏ Scorpio.
17 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
1 day after previous North standstill on 18 March 2013 at 21:50 in ♊ Gemini, when Moon has reached northern declination of ∠20.335°. Next 12 days the lunar orbit moves southward to face South declination of ∠-20.250° in the next southern standstill on 1 April 2013 at 12:03 in ♐ Sagittarius.
After 6 days on 27 March 2013 at 09:27 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
