This is a development from the use of the Kp index and a wet finger (or damp rabbit's paw !!) is thanks to some pointers from a member of the VLF (natural radio) community. The paper can be found on my web site at http://www.alan.melia.btinternet.co.uk/DstIndex.htm Earlier propagation and general articles can be found through links from the home page http://www.alan.melia.btinternet.co.uk Cheers de Alan G3NYK alan.melia@btinternet.com
