Solar-Terrestrial Data:
  1. Paul Herrman, N0NHB, has 19 Solar-Terrestrial Data banners available at  https://www.hamqsl.com/solar.html 
  2. A glossary of terms for the data in the Solar banners is at  https://www.hamqsl.com/solar2.html#glossary 
  3. A table linking the content in the Solar-Terresstrial Data banners to HF/VHF Propagation conditions can be found by going to  https://www.hamqsl.com/FAQ.html#Solar and scrolling down to the "Where can I find information on the data provided in the banner?" bullet item.
  4. Another space weather website is  https://spaceweather.com/ 
  5. K7RA weekly Solar Update posted Fridays on  http://arrl.net/ Look in the "Latest News" window for the latest "The K7RS Solar Update" posting.
  6.  http://arrl.org/propagation-of-rf-signals has links to a number of propagation articles.
  7. Find the article "What The Numbers Mean, and Propagation Predictions -- a brief introduction to propagation and the major factors affecting it" at  http://arrl.org/the-sun-the-earth-the-ionosphere 
  8. Carl Luetzelschwab, K9LA, has a website devolted to Amateur Radio Propagation. check it out at  http://k9la.us/ .
