gibbous phase

(gĭb`əs): see phasephase,
in astronomy, the measure of how much of the illuminated surface of a planet or satellite can be seen from a point at a distance from that body; the term is most often used to describe the moon as seen from the earth.

The phase of an outer planet is always full or gibbous (more than half but not all of the disc illuminated); the gibbous phase is quite pronounced on Mars, but less so on the more distant planets.
30am on 13/14 December, but notes that the moon is in the Waxing Gibbous phase, which may interfere with viewing.
Observation of the large gibbous phase at the start of this elongation will be favourable, as early indications from 2013 May onwards have already shown, but when the planet reaches greatest elongation on 2013 Nov 1 it will be in extreme south declination.
The moon will probably spoil much of the event this time around, because it's in gibbous phase and will illuminate 85 percent of the night sky, Space.
The large gibbous phase is therefore often under-observed, yet records of this phase are those most easily able to define the shape and extent of the characteristic, large Y- and psi-shaped dark markings which can almost always be seen in the ultraviolet and glimpsed--in part at least--in white light.
com pointed out, the moon is in a waxing gibbous phase, which could result in a lot of light across the night sky, making it hard to see the meteor shower during its early peak hours.
Its initially high northerly declination enabled observations of the large gibbous phase, and several repeated observations of the dark markings were made, showing the four-day period well in evidence.
Declination throughout the high gibbous phase was not favourable: very few UK observations were made before 2008 December, and none at all were suitable for measuring the UV rotation period as a function of latitude.
The phase of an superior planet is always full or gibbous (more than half of the disk illuminated); the gibbous phase is quite pronounced on Mars, but less so on the more distant planets.
The phase of an outer planet is always full or gibbous (more than half but not all of the disk illuminated); the gibbous phase is quite pronounced on Mars, but less so on the more distant planets.
Waxing gibbous phase, rises after noon, sets before dawn, highest in the sky during late evening.
