Quarter ♏ Scorpio
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 50% and growing larger. The 7 days young Moon is in ♏ Scorpio.
* The exact date and time of this First Quarter phase is on 23 July 2091 at 13:02 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠0° of ♏ Scorpio tropical zodiac sector.
Lunar disc appears visually 4.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1889".
Next Full Moon is the Buck Moon of July 2091 after 7 days on 30 July 2091 at 12:01.
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 1132 of Meeus index or 2085 from Brown series.
Length of current 1132 lunation is 29 days, 10 hours and 6 minutes. It is 53 minutes longer than next lunation 1133 length.
Length of current synodic month is 2 hours and 38 minutes shorter than the mean length of synodic month, but it is still 3 hours and 31 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠280.5°. At the beginning of next synodic month true anomaly will be ∠310.2°. 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°).
Moon is reaching point of perigee on this date at 04:02, this is 13 days after last apogee on 9 July 2091 at 13:01 in ♈ Aries. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 13 days ahead, until it will get to the point of next apogee on 6 August 2091 at 07:42 in ♉ Taurus.
This perigee Moon is 369 671 km (229 703 mi) away from Earth. This is the year's farthest perigee of 2091. It is 7 163 km closer than the mean perigee distance, but it is still 685 km farther than the closest perigee of 21st century.
4 days after its ascending node on 19 July 2091 at 10:20 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 1 August 2091 at 10:40 in ♓ Pisces.
4 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.
8 days after previous North standstill on 15 July 2091 at 05:57 in ♋ Cancer, when Moon has reached northern declination of ∠18.955°. Next 4 days the lunar orbit moves southward to face South declination of ∠-18.921° in the next southern standstill on 28 July 2091 at 05:06 in ♑ Capricorn.
After 7 days on 30 July 2091 at 12:01 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
