Gibbous ♋ Cancer
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 ♋ Cancer.
* The exact date and time of this First Quarter phase is on 19 March 2100 at 02:58 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing first ∠3° of ♋ Cancer tropical zodiac sector.
Lunar disc appears visually 4.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1927".
Next Full Moon is the Worm Moon of March 2100 after 6 days on 26 March 2100 at 01:05.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1239 of Meeus index or 2192 from Brown series.
Length of current 1239 lunation is 29 days, 17 hours and 48 minutes. This is the year's longest synodic month of 2100. It is 1 hour and 11 minutes longer than next lunation 1240 length.
Length of current synodic month is 5 hours and 4 minutes longer than the mean length of synodic month, but it is still 1 hour and 59 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠151.4°. At beginning of next synodic month true anomaly will be ∠176.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
5 days after point of apogee on 13 March 2100 at 21:09 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 7 days, until it get to the point of next perigee on 26 March 2100 at 14:59 in ♎ Libra.
Moon is 389 833 km (242 231 mi) away from Earth on this date. Moon moves closer next 7 days until perigee, when Earth-Moon distance will reach 357 415 km (222 087 mi).
8 days after its ascending node on 10 March 2100 at 16:27 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 5 days, until it will cross the ecliptic from North to South in descending node on 24 March 2100 at 20:18 in ♍ Virgo.
8 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the beginning to the first part of it.
At 01:51 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠28.566°. This is the year's northernmost lunar standstill of 2100. Next 12 days the lunar orbit will move in opposite southward direction to face South declination of ∠-28.525° in its southern standstill point on 31 March 2100 at 15:42 in ♐ Sagittarius.
After 6 days on 26 March 2100 at 01:05 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
