Statistical study of the solar eclipses over Egypt during 20 centuries (1–2000)

摘要

During solar eclipses the scientists can be observe and studying the solar atmosphere. The stratified structures of the solar atmosphere are mainly the photosphere, the chromosphere and the corona. In this work we used the Least Square (LS) method to investigate the statistical study of the solar eclipses during 20 centuries (1–2000). We found the formula for total number of every types of solar eclipse. We get the frequency distribution of all eclipses for 20 centuries over Egypt; the percentage ratio for partial solar eclipse is 43.2%, while the percentage ratio for the annular solar eclipse is 30.1%, and the percentage ratio for total and hybrid solar eclipses are 22.3% and 4.4% respectively. The General Linear Trend formula for predicting the future values for every types of solar eclipse was obtained and determined during next 500 years (2001–2500). We compare our results with calculated once by NASA for each types of solar eclipse. Our results are in a good agreement with that published by NASA.
