Reading Solar-Terrestrial Data Blocks

If you are into DX work, you are probably familiar with the solar-terrestrial blocks that tell you the K and A indices but do you know what all the other data is? What significance does the XRAY index have? What is a 304A reading? If you know the answers to these questions, join us Thursday for a discussion of these indices along with the other data in those little blocks.

Here are a few links to get you started

I've just set up a new Solar Page that aggregates all the information found in these links and you may find helpful for getting propagation conditions. You can access this page under the SMRC Content tab.
