Quarter ♒ Aquarius
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 51% and growing larger. The 7 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 10 October 2100 at 08:33 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠19° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 0.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1913" and ∠1922".
Next Full Moon is the Hunter Moon of October 2100 after 7 days on 18 October 2100 at 04:06.
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 1246 of Meeus index or 2199 from Brown series.
Length of current 1246 lunation is 29 days, 9 hours and 12 minutes. This is the year's shortest synodic month of 2100. It is 34 minutes shorter than next lunation 1247 length.
Length of current synodic month is 3 hours and 32 minutes shorter than the mean length of synodic month, but it is still 2 hours and 37 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠340.4°. At the beginning of next synodic month true anomaly will be ∠356.4°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
5 days after point of perigee on 4 October 2100 at 21:58 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 20 October 2100 at 04:03 in ♉ Taurus.
Moon is 374 654 km (232 799 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 406 359 km (252 500 mi).
8 days after its descending node on 1 October 2100 at 12:43 in ♍ Virgo, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 14 October 2100 at 06:36 in ♓ Pisces.
23 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the second to the final part of it.
1 day after previous South standstill on 8 October 2100 at 20:58 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.233°. Next 12 days the lunar orbit moves northward to face North declination of ∠28.129° in the next northern standstill on 23 October 2100 at 08:12 in ♊ Gemini.
After 7 days on 18 October 2100 at 04:06 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
