Quarter ♈ Aries
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 47% and growing larger. The 7 days young Moon is in ♓ Pisces.
* The exact date and time of this First Quarter phase is on 22 December 2001 at 20:56 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is leaving the last ∠3° of ♓ Pisces tropical zodiac sector and will enter ♈ Aries later.
Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1951".
Next Full Moon is the Cold Moon of December 2001 after 7 days on 30 December 2001 at 10:41.
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 24 of Meeus index or 977 from Brown series.
The length of the lunation is 29 days, 16 hours and 41 minutes. It is 1 hour and 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 3 hours and 57 minutes longer than the mean synodic month length. It is 3 hours and 6 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠86.2°. At the beginning of next synodic month the true anomaly is going to be ∠123.9°.
1 day after point of apogee on 21 December 2001 at 13:02 in ♓ Pisces. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 2 January 2002 at 07:13 in ♌ Leo.
The Moon is 404 908 km (251 598 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 412 km (227 056 mi).
7 days after descending node on 15 December 2001 at 04:32 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following 7 days, until the lunar orbit crosses from South to North in ascending node on 29 December 2001 at 14:51 in ♊ Gemini.
20 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.
6 days since the previous standstill on 16 December 2001 at 07:51 in ♑ Capricorn when the Moon has reached South declination of ∠-24.250°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠24.244° at the point of next northern standstill on 30 December 2001 at 15:40 in ♋ Cancer.
In 7 days on 30 December 2001 at 10:41 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.
