A large sunspot with an apparent diameter of 100,000 km forms on the photospheric disk of the Sun. Its effective temperature is 1700 K cooler than the surrounding photosphere which has an effective temperature of 5700 K.
(a) Calculate the percentage reduction in the solar constant, measured at the Earth, as a result of this sunspot. Use a solar photosphere radius of 7x10^5 km.
in this case the energy emanated by the sun is the
total area of the photosphere x [tex] \sigma T^4 [/tex]
to get the usual solar consant we simply divide by 4
the change in the solar constant would be to subtract the deficit?
