Gibbous ♉ Taurus
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 55% and growing larger. The 8 days young Moon is in ♉ Taurus.
* The exact date and time of this First Quarter phase is on 18 January 2013 at 23:45 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠5° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 8.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1791" and ∠1950".
Next Full Moon is the Wolf Moon of January 2013 after 7 days on 27 January 2013 at 04:38.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 161 of Meeus index or 1114 from Brown series.
The length of the lunation is 29 days, 11 hours and 36 minutes. It is 55 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 and 8 minutes shorter than the mean synodic month length. It is 5 hours and 1 minute longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠23.3°. At the beginning of next synodic month the true anomaly is going to be ∠44.2°.
9 days after point of perigee on 10 January 2013 at 10:26 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next apogee on 22 January 2013 at 10:52 in ♊ Gemini.
The Moon is 400 286 km (248 726 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 313 km (251 850 mi).
11 days after ascending node on 7 January 2013 at 23:50 in ♏ Scorpio. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 21 January 2013 at 01:19 in ♉ Taurus.
11 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
9 days since the previous standstill on 9 January 2013 at 15:22 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.879°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠20.816° at the point of next northern standstill on 23 January 2013 at 05:12 in ♊ Gemini.
In 7 days on 27 January 2013 at 04:38 in ♌ Leo 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.
