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 19 December 2099 at 14:22 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1950".
Next Full Moon is the Cold Moon of December 2099 after 8 days on 27 December 2099 at 12:58.
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 1236 of Meeus index or 2189 from Brown series.
The length of the lunation is 29 days, 13 hours and 47 minutes. It is 2 hours and 12 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 3 minutes longer than the mean synodic month length. It is 6 hours shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠49.8°. At the beginning of next synodic month the true anomaly is going to be ∠81.3°.
10 days after point of perigee on 8 December 2099 at 17:50 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 20 December 2099 at 13:16 in ♈ Aries.
The Moon is 404 808 km (251 536 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 339 km (251 245 mi).
Moon is in ascending node in ♓ Pisces at 01:02 crossing the ecliptic from South to North to meet descending node 13 days later on 1 January 2100 at 21:13 in ♍ Virgo.
At 01:02 the Moon completes the previous draconic month and enters the new one.
6 days since the previous standstill on 12 December 2099 at 13:59 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.351°, the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠28.345° at the point of next northern standstill on 26 December 2099 at 23:34 in ♊ Gemini.
In 8 days on 27 December 2099 at 12:58 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.
