I have had some very confusing plots from SXV during this period. Last night I had good solid high levels from SXV with very little sign of multipath. There was a geomag storm on the 19th at around midday. I would not expect that to start giving absorption before 21/22nd I think that I may have been seeing a lot of destructive interference previously but maybe last night there was more absorption taking down the high-hop paths. The only thing that might be connected to this is a small proton event again at midnight, but again this would not be in impact with the correct geographical part of the ionosphere. (too far west) In conclusion I think propagation might be ok tonight but will decline afterwards for a few days. Unfortunately electric storms in east USA will probably cancel out the advantageous propagation. Not too helpful but I would be interested to see Steve's plots on DCF39 on that side to see whether it conforms to my thoughts. Happy DXing and Cheers de Alan G3NYK alan.melia@btinternet.com
