Comment on: “Electrical coupling of the E- and F-regions”: by R. A. Heelis,P. C. Kendall,R. J. Moffett,D. W. Windle and H. Rishbeth

New measurements have been made of the reduced polarization in a Fraunhofer line (Hβ) of blue sky light. The value of the depolarization agrees well with a previously reported intensity filling-in effect. There is no evidence of a change of the azimuth of vibration of the polarization across the line profile.
