First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 54% and growing larger. The 8 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 13 October 2021 at 03:25 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠25° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1924".
Next Full Moon is the Hunter Moon of October 2021 after 7 days on 20 October 2021 at 14:57.
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 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.
Length of current 269 lunation is 29 days, 10 hours and 9 minutes. This is the year's shortest synodic month of 2021. It is 19 minutes shorter than next lunation 270 length.
Length of current synodic month is 2 hours and 35 minutes shorter than the mean length of synodic month, but it is still 3 hours and 34 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠323.3°. At the beginning of next synodic month true anomaly will be ∠342.3°. 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°).
4 days after point of perigee on 8 October 2021 at 17:28 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 24 October 2021 at 15:30 in ♊ Gemini.
Moon is 369 064 km (229 326 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 405 616 km (252 038 mi).
3 days after its descending node on 9 October 2021 at 19:35 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 23 October 2021 at 11:47 in ♊ Gemini.
17 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
1 day after previous South standstill on 12 October 2021 at 09:09 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.204°. Next 13 days the lunar orbit moves northward to face North declination of ∠26.291° in the next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.
After 7 days on 20 October 2021 at 14:57 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
