N2  - In the previous paper (pp. 455-62 of the present issue) the authors have shown that the total ionospheric absorption of cosmic noise at 28·6 MHz can be expressed as a sum of three contributions: from the F2 layer (including topside ionosphere), from the D and E layers, and from abnormal phenomena such as spread-F; and can be given by the expression
