From Bill Whitacre via hard-core-dx.com:
If you're interested in radio propagation and how geomagnetic indices effect
what you hear on mediumwave, there's a project you should know about.
Graphs of the last 60 days of the daily average of the 2MeV electron flux,
A-index, K-index, Dst and solar wind plus a numerical index of Nick Hall-Patch's
daily Victoria, BC TP and DU reception quality can be found here:
http://tivodxer.com/jpgraph_example_multigraph1.phpNot only are pertinent geomagnetic indices shown on the same page for the same
period for your comparison, but we've added actual reception data to the graph.
Our hope is that this will allow us to find some new correlations between
reception and what the sun is doing, as well as validate or refute some existing
theories.
Involved in this project are Nick Hall-Patch as chief scientific consultant and
contributor of the reception index, Mauno Ritola as sanity check and contribitor
of the 2MeV electron flux, and Bill Whitacre as curator and 'scraper' of data.
In the works is a way to let you select a date range and get back results.
We're also interested in your observations that confirm or refute 'common
widsom' about propagation.
