First signs as the local noise subsided was an "M" at -0130ish then "O" right through to the end of the last string seen finishing at about 0645z. There was a deep fade which took out the last three dashes of the "1" at around 0400z. It is interesting that looking at Steve Dove's trace of DCF39 he shows a deep fade also at about 0345z. I think this is a manifestation of what I call the "boing" effect. I think the ionosphere is "ringing" after the collision yesterday with the CME from the X-Class flare. You can see a very rapid fading with a period of about 15 minutes on Steve's plot. There are probably lots of harmonics and the they all added to give a multipath extinction at around 0400z. I picked a program up from one of the Univ Iono-physics sites which draws a pictiure of a "ringing" sphere....very pretty !! Good Show Cheers de Alan G3NYK alan.melia@btinternet.com
