          For my hamateur radio and SWL friends around the globe:

          I have decided to begin posting some of my daily solar, space
          and geomagnetic weather discussions and HF radio wave
          propagation forecasts in my Twitter account at @GiellaW4hm .
          Of course it will consist of little snippets of what's going
          on as Twitter severely limits tweets as far as content length.

          Feel free to redistribute this "not for profit" solar, space
          and geomagnetic weather discussion and HF radio wave
          propagation forecast, as long as you redistribute it in it's
          entirety and give me credit for it.

          Also feel free to leave a "LIKE" every time you access this
          discussion and forecast as it's the only method I have to
          gauge the usefulness of it.
