When a band closes, there is often some remaining backscatter. This comes from the edge of the skipzone whre there is still daylight. The following plot was done on 29 November 2002 at a frequency of 3808kHz. It shows backscatter during the night and finally shows normal propagation resuming at local sunrise. The shapes of the backscatter structures are interesting and similar to those on other plots that I have seen. It would be interesting to make a study of backscatter with a view to investigating its causes and to determine the mechanisms in some detail.
