First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 58% and growing larger. The 8 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 22 September 2023 at 19:32 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠9° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1912".
Next Full Moon is the Harvest Moon of September 2023 after 5 days on 29 September 2023 at 09:57.
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 293 of Meeus index or 1246 from Brown series.
Length of current 293 lunation is 29 days, 16 hours and 15 minutes. This is the year's longest synodic month of 2023. It is 43 minutes longer than next lunation 294 length.
Length of current synodic month is 3 hours and 31 minutes longer than the mean length of synodic month, but it is still 3 hours and 32 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠202.9°. At the beginning of next synodic month true anomaly will be ∠232.5°. 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°).
10 days after point of apogee on 12 September 2023 at 15:42 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 28 September 2023 at 01:05 in ♓ Pisces.
Moon is 369 892 km (229 840 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 359 911 km (223 638 mi).
5 days after its descending node on 17 September 2023 at 19:18 in ♎ Libra, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 30 September 2023 at 16:49 in ♈ Aries.
20 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the second to the final part of it.
At 03:42 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.254°. Next 12 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.294° in its northern standstill point on 5 October 2023 at 20:31 in ♊ Gemini.
After 5 days on 29 September 2023 at 09:57 in ♈ Aries, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
