Recent observations have evidenced "hotter" zones in our Sun's atmosphere. There, temperature can be as high as a million Kelvin, rather than 10,000 K, as would be normal on the average of the Sun's chromosphere. Such fluctuations are attributed to the local release  of energy, due to magnetic reconnection. Researches on the temperature distribution in the Sun's external atmosphere have originated with the launch of the IRIS satellite, which looks at the Sun through an ultraviolet "eye". Previous results have reported temperature fluctuations, but never that high.
