The temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF).So basically at the bottom it is 200K. At the top it is 500K.K is in Kelvin.he temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF). So basically at the bottom it is 200K.

The temperature here drops below 3.5 million degrees F (2 million degrees C). Large bubbles of hot plasma form a soup of ionized atoms and move upwards to the photosphere. The temperature in the photosphere is about 10,000 degrees F (5,500 degrees C).It is here that the sun's radiation is detected as sunlight. Sunspots on the photosphere are cooler and darker than the surrounding area. At the center of big sunspots the temperature can be as low as 7,300 degrees F (4,000 degrees C).The chromosphere, the next layer of the sun's atmosphere is a bit cooler â about 7,800 degrees F (4,320 degrees C).t is here that the sun's radiation is detected as sunlight. Sunspots on the photosphere are cooler and darker than the surrounding area. At the center of big sunspots the temperature can be as low as 7,300 degrees F (4,000 degrees C).
