Quarter ♉ Taurus
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♉ Taurus.
* The exact date and time of this First Quarter phase is on 23 January 2010 at 10:53 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠4° of ♉ Taurus tropical zodiac sector.
Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1854" and ∠1949".
Next Full Moon is the Wolf Moon of January 2010 after 6 days on 30 January 2010 at 06:18.
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 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 124 of Meeus index or 1077 from Brown series.
The length of the lunation is 29 days, 19 hours and 40 minutes. This is the year's longest synodic month of 2010. It is 1 hour and 30 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 6 hours and 56 minutes longer than the mean synodic month length. It is 7 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠164.3°. At the beginning of next synodic month the true anomaly is going to be ∠188.9°.
6 days after point of apogee on 17 January 2010 at 01:40 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next perigee on 30 January 2010 at 09:03 in ♌ Leo.
The Moon is 386 518 km (240 171 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 593 km (221 577 mi).
8 days after ascending node on 14 January 2010 at 23:18 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 29 January 2010 at 00:02 in ♋ Cancer.
8 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.
11 days since the previous standstill on 12 January 2010 at 08:33 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.796°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠25.783° at the point of next northern standstill on 26 January 2010 at 21:04 in ♊ Gemini.
In 6 days on 30 January 2010 at 06:18 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.
