Solar Camera Was Self-contained: The most popular type of solar Camera was self-contained in a lighttight box; it could be set up outdoors, usually on the studio roof. Exposures were hours, sometimes even days long, and it was the job of apprentices to keep the apparatus pointed directly toward the sun.
Beyond the chromosphere is the corona, a region of tenuous gas stretching millions of kilometers above the solar disk. At any particular moment there may be as many as 100,000 spicules (jets of gas) shooting out of the chromosphere into the corona to heights of 10,000 km (6,214 mi). There are also solar flares, sudden great bursts of energy that occur most often during periods of solar activity.
Spanning an area of 200,000 sq. ft., the building to be operational in April 2006 will showcase the 100 KW use of solar energy for Lighting and solar-thermal for 100 Tons of air-conditioning.
