Quarter ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 49% and growing larger. The 7 days young Moon is in ♓ Pisces.
* The exact date and time of this First Quarter phase is on 18 December 2015 at 15:14 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠24° of ♓ Pisces tropical zodiac sector.
Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1950".
Next Full Moon is the Cold Moon of December 2015 after 6 days on 25 December 2015 at 11:11.
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 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 197 of Meeus index or 1150 from Brown series.
The length of the lunation is 29 days, 15 hours and 1 minute. It is 1 hour and 53 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 2 hours and 17 minutes longer than the mean synodic month length. It is 4 hours and 46 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠255.6°. At the beginning of next synodic month the true anomaly is going to be ∠292.2°.
12 days after point of apogee on 5 December 2015 at 14:56 in ♎ Libra. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 21 December 2015 at 08:53 in ♉ Taurus.
The Moon is 364 238 km (226 327 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 368 418 km (228 924 mi).
Moon is in descending node in ♓ Pisces at 15:13 crossing the ecliptic from North to South to meet ascending node 13 days later on 31 December 2015 at 20:19 in ♍ Virgo.
13 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the second to the final part of the cycle.
6 days since the previous standstill on 12 December 2015 at 08:15 in ♑ Capricorn when the Moon has reached South declination of ∠-18.438°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠18.444° at the point of next northern standstill on 25 December 2015 at 07:30 in ♋ Cancer.
In 6 days on 25 December 2015 at 11:11 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.
