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 ♍ Virgo.
* The exact date and time of this First Quarter phase is on 31 May 2009 at 03:22 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠15° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 1.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1924" and ∠1892".
Next Full Moon is the Strawberry Moon of June 2009 after 7 days on 7 June 2009 at 18:12.
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 116 of Meeus index or 1069 from Brown series.
Length of current 116 lunation is 29 days, 7 hours and 24 minutes. It is 24 minutes longer than next lunation 117 length.
Length of current synodic month is 5 hours and 20 minutes shorter than the mean length of synodic month, but it is still 49 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠332.7°. At the beginning of next synodic month true anomaly will be ∠349.4°. 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 26 May 2009 at 03:44 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 10 June 2009 at 16:04 in ♑ Capricorn.
Moon is 372 460 km (231 436 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 405 786 km (252 144 mi).
3 days after its descending node on 28 May 2009 at 10:19 in ♌ Leo, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 11 June 2009 at 10:15 in ♒ Aquarius.
16 days after beginning of current draconic month in ♒ Aquarius, the Moon is moving from the second to the final part of it.
5 days after previous North standstill on 25 May 2009 at 16:56 in ♊ Gemini, when Moon has reached northern declination of ∠26.451°. Next 7 days the lunar orbit moves southward to face South declination of ∠-26.429° in the next southern standstill on 8 June 2009 at 02:03 in ♐ Sagittarius.
After 7 days on 7 June 2009 at 18:12 in ♐ Sagittarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
