Abstract An analysis was made of modal interference patterns observed during sunrise transitions on transequatorial propagation paths where the receiver was south and west of the transmitter. The phase difference, at the receiver, between the interfering modes was obtained as a function of the distance of the sunrise line along the path from the transmitter, and was found to have a turning point when the sunrise line was in the vicinity of the magnetic equator. This tended to confirm the existence of an equatorial anomaly, as suggested by Lynn, in VLF propagation on such paths. The analysis suggested that there was a reduction in the phase velocity of the second order mode while propagating through the equatorial region, the phase velocity of the first order mode remaining essentially unaltered.
