Estimating the size of Earth’s umbral shadow using sky brightness light curves during a lunar eclipse
We present a simple method to estimate the size of Earth’s umbral shadow in a classroom setting. The method uses the published sky brightness curves obtained during a total lunar eclipse and requires only a conceptual understanding of lunar eclipses and simple geometric considerations. It is suitable for use in introductory and upper level astronomy courses.
