Gibbous ♋ Cancer
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.
The length of the lunation is 29 days, 13 hours and 44 minutes. It is 1 hour and 9 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour longer than the mean synodic month length. It is 6 hours and 3 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠73.6°. At the beginning of next synodic month the true anomaly is going to be ∠110.3°.
1 day after point of apogee on 19 March 2013 at 03:13 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 31 March 2013 at 03:55 in ♐ Sagittarius.
The Moon is 404 464 km (251 322 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 367 494 km (228 350 mi).
4 days after descending node on 16 March 2013 at 06:15 in ♉ Taurus. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 30 March 2013 at 05:55 in ♏ Scorpio.
17 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
1 day since the previous standstill on 18 March 2013 at 21:50 in ♊ Gemini when the Moon has reached North declination of ∠20.335°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-20.250° at the point of next southern standstill on 1 April 2013 at 12:03 in ♐ Sagittarius.
In 6 days on 27 March 2013 at 09:27 in ♎ Libra 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.
