Dawn needs solar illumination for imaging and some mapping activities.

The falling was accompanied by a bright, blinding flare brighter than solar illumination and a noise similar to rolling thunder.

A low angle of solar illumination and a high viewing angle make possible discrimination of topographic detail near the terminator.

Higher angles of solar illumination and lower viewing angles make it increasingly difficult to discern topographic variations to the west.

Dr. Olsen's efforts resulted in GaAs cells that were greater than 21% efficient when coupled to simulated solar illumination.

The rim of Shackleton Crater, towards the Lunar south pole, also has a near-constant solar illumination.

Because of this, the Moon's solar illumination varies much less with season, and topographical details play a crucial role in seasonal effects.

In long distance remote sensing with solar illumination the atmosphere absorbs energy in certain bands and only the remaining 'windows' are available.

Such reconstruction takes into consideration complex interactions among environmental factors such as temperatures, food supplies, and degree of solar illumination.

Straying of tigers into nearby villages is prevented through measures such as nylon net fencing and solar illumination of villages.
