Directed toward center of the Earth. View angle is +-4.5 degrees. The data from the sensor should not be used for the lit parts of the orbit since intensity of the dispersed sunlight here is higher than the normally measured intensity of light from nitrogen N2+. Also the sensor lost his sensitivity with time so that after March 1978 it may be used only for indicating of the lit and shadowed parts of the orbit. ********************************
