First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 25 February 2015 at 17:14 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠4° of ♊ Gemini tropical zodiac sector.
Next Full Moon is the Worm Moon of March 2015 after 8 days on 5 March 2015 at 18:06.
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.
Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1882" and ∠1938".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 187 of Meeus index or 1140 from Brown series.
The length of this lunation is 29 days, 9 hours and 49 minutes and it is 28 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 2 hours and 55 minutes shorter than the mean synodic month length. It is 3 hours and 14 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠354.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠9.9°.
6 days since point of perigee on 19 February 2015 at 07:29 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 5 March 2015 at 07:35 in ♍ Virgo.
The Moon is 380 908 km (236 685 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 386 km (252 517 mi).
3 days after descending node on 21 February 2015 at 16:05 in ♈ Aries the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 7 March 2015 at 21:04 in ♎ Libra.
10 days since the last southern standstill on 14 February 2015 at 17:17 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.402° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.335° at the point of next northern standstill on 27 February 2015 at 07:19 in ♊ Gemini.
16 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.
In 8 days on 5 March 2015 at 18:06 in ♍ Virgo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
