Abstract Regular signal fading during sunrise and sunset transitions was observed at middle latitude VLF receiving sites. The amplitude ratio E2 E1 of the two modal components producing the observed fading was obtained at frequencies ranging from 12.2 to 23.4 kHz. This ratio proved to be essentially independent of the direction of propagation, with sunrise values being some 7 dB greater than at sunset. The experimentally obtained values of E2 E1, together with the physical location and horizontal dimensions of the change in reflection height at sunrise and sunset, were compared with values derived from theoretical models. Approximate agreement was found.
