Abstract: | Measurements of the direct solar radiation during the annular solar eclipse of April 29, 1976 are given in three wavelength bands (centered on 800, 680, and 450 nm). A decrease of the solar radiation after the last contact was observed, especially in the red and infrared. This is considered in connection with the results of other direct light and zenith light measurements. |
