Gibbous ♊ Gemini
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 61% and growing larger. The 8 days young Moon is in ♊ Gemini.
* The exact date and time of this First Quarter phase is on 17 February 2100 at 09:22 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠12° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1941".
Next Full Moon is the Snow Moon of February 2100 after 6 days on 24 February 2100 at 14:51.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1238 of Meeus index or 2191 from Brown series.
Length of current 1238 lunation is 29 days, 17 hours and 34 minutes. It is 14 minutes shorter than next lunation 1239 length.
Length of current synodic month is 4 hours and 50 minutes longer than the mean length of synodic month, but it is still 2 hours and 13 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠119.1°. At beginning of next synodic month true anomaly will be ∠151.4°. 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°).
4 days after point of apogee on 14 February 2100 at 06:46 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 26 February 2100 at 05:17 in ♍ Virgo.
Moon is 395 838 km (245 962 mi) away from Earth on this date. Moon moves closer next 7 days until perigee, when Earth-Moon distance will reach 360 805 km (224 194 mi).
7 days after its ascending node on 11 February 2100 at 09:33 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 25 February 2100 at 09:12 in ♍ Virgo.
7 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the beginning to the first part of it.
13 days after previous South standstill on 5 February 2100 at 04:00 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.496°. Next day the lunar orbit moves northward to face North declination of ∠28.552° in the next northern standstill on 19 February 2100 at 17:35 in ♊ Gemini.
After 6 days on 24 February 2100 at 14:51 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
