From data obtained during the eclipse and on control days, the effective coefficient of recombination for F-2 layer is found to be 4×10-10 cm3/electron per sec. The magnitude of a is apparently a function of the height of the layer which becomes lower with increasing latitude. Solar eruptions may be associated with two of the discontinuities of the eclipse curve. The thickness of the F-2 layer became compressed and dropped as a whole during the eclipse, possibly due to air movement caused by lowering of temperature. The sporadic E layer was not influenced by the change of solar radiation, and must be due to other causes.
