Abstract: The purpose of this paper is to discuss the measured irradiance during the eclipse and to compare the irradiance with a simple straightforward model that estimates the effect of the eclipse on solar radiation. The intended audience of this paper is for high school and university educators that want to give their students a simple model to predict the effects the eclipse has on the light reaching the earth. The paper is outlined as follows. First a general overview of irradiance on a non-eclipse day and an eclipse day will be discussed. Next, a straightforward model of the eclipse will be used to predict the irradiance during an eclipse from a clear sky model. Lastly, the modeled irradiance will be compared to the measured irradiance and the results will be discussed.
