Tonight there are strong aurora which can be heard on signals and I notice that the signals track spread out over maybe 3 to 5 hz and I have very few succesful decodes.

Only the strongest signals are successfully decoded, a lot of signals which would normally be decoded are not
decoded. See attached screenshot from 80m tonite 27feb at around 2300 utc. As you can see the tracks are much wider than normal.

At the same time it seems my signal is reasonably well decoded to the south. But I notice that the east west path is blocked, see attached map, normally the finnish stations (OH) has good decodes here and they decode my signal.

Does anybode know how wspr react on aurora distorted signals?
