Quarter ♉ Taurus
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and growing larger. The 8 days young Moon is in ♉ Taurus.
* The exact date and time of this First Quarter phase is on 31 January 2012 at 04:10 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠15° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1948".
Next Full Moon is the Snow Moon of February 2012 after 7 days on 7 February 2012 at 21:54.
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 149 of Meeus index or 1102 from Brown series.
The length of the lunation is 29 days, 14 hours and 55 minutes. It is 1 hour and 8 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 2 hours and 11 minutes longer than the mean synodic month length. It is 4 hours and 52 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠70.8°. At the beginning of next synodic month the true anomaly is going to be ∠107.8°.
1 day after point of apogee on 30 January 2012 at 17:42 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 11 February 2012 at 18:32 in ♎ Libra.
The Moon is 405 192 km (251 775 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 367 920 km (228 615 mi).
11 days after ascending node on 19 January 2012 at 18:26 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 2 days, until the lunar orbit crosses from North to South in descending node on 2 February 2012 at 20:02 in ♊ Gemini.
11 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.
11 days since the previous standstill on 20 January 2012 at 02:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.492°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠22.404° at the point of next northern standstill on 3 February 2012 at 07:11 in ♊ Gemini.
In 7 days on 7 February 2012 at 21:54 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.
