It looks from your pic as though there was data on the lowest "channel" last night. Previous nights and certainly when it first appeared here last night it was just the lines. I have a plot of last night, and whilst there was a lot of deep fading in the middle of the night the level reached an almost record peak of over 40dBuV here at one stage before dawn. The plot will be posted to my propagation page soon. I think out Trans-Atlantic friends are beginning to suffer from its "spread" like some stations suffer the effects of Lessay, Sylt and DCF39 in Europe. It does confirm that conditions are quite good at the moment and improving, but there is a cloud on the horizon as there was an M5 flare early yesterday.
