Quarter ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 48% and growing larger. The 7 days young Moon is in ♈ Aries.
* The exact date and time of this First Quarter phase is on 24 December 2009 at 17:36 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠0° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 7.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1805" and ∠1951".
Next Full Moon is the Cold Moon of December 2009 after 7 days on 31 December 2009 at 19:13.
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 123 of Meeus index or 1076 from Brown series.
The length of the lunation is 29 days, 19 hours and 9 minutes. This is the year's longest synodic month of 2009. It is 31 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 6 hours and 25 minutes longer than the mean synodic month length. It is 38 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠135.6°. At the beginning of next synodic month the true anomaly is going to be ∠164.3°.
3 days after point of apogee on 20 December 2009 at 14:54 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 8 days, until the Moon reaches the point of next perigee on 1 January 2010 at 20:36 in ♋ Cancer.
The Moon is 397 030 km (246 703 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 358 684 km (222 876 mi).
5 days after ascending node on 18 December 2009 at 16:41 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 1 January 2010 at 12:30 in ♋ Cancer.
5 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.
8 days since the previous standstill on 16 December 2009 at 02:38 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.769°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠25.787° at the point of next northern standstill on 30 December 2009 at 10:09 in ♊ Gemini.
In 7 days on 31 December 2009 at 19:13 in ♋ Cancer 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.
