Quarter ♉ Taurus
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 21 January 2002 at 17:47 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Lunar disc appears visually 8.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1950".
Next Full Moon is the Wolf Moon of January 2002 after 7 days on 28 January 2002 at 22:50.
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 25 of Meeus index or 978 from Brown series.
Length of current 25 lunation is 29 days, 18 hours and 12 minutes. It is 10 minutes shorter than next lunation 26 length.
Length of current synodic month is 5 hours and 28 minutes longer than the mean length of synodic month, but it is still 1 hour and 35 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠123.9°. At beginning of next synodic month true anomaly will be ∠155.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
3 days after point of apogee on 18 January 2002 at 08:50 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 30 January 2002 at 09:02 in ♍ Virgo.
Moon is 399 744 km (248 389 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 359 997 km (223 692 mi).
10 days after its descending node on 11 January 2002 at 11:56 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 26 January 2002 at 00:27 in ♋ Cancer.
22 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
8 days after previous South standstill on 12 January 2002 at 15:26 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.240°. Next 5 days the lunar orbit moves northward to face North declination of ∠24.270° in the next northern standstill on 27 January 2002 at 01:56 in ♋ Cancer.
After 7 days on 28 January 2002 at 22:50 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
