      I have had the same questions as you have Barry. However, the graph is more informative to me so I never asked Alex about this.

      Sorry, but I'm confused now. I'm not sure which maps are "real time"
      and which are "monthly." Normally, when I use Hamcap, I click on
      "IonoProbe" on the settings page so that Hamcap has current prop data.
      On the map page, I usually click on the "real time" arrow to get the
      current prediction. On the map page, if I click on the left or right
      arrows to move backward or forward an hour, are those maps "real time"
      or "monthly"? Do these hourly maps utilize the Ionoprobe data? If
      they do utilize the Ionoprobe data, won't they change whenever the
      data from Ionoprobe changes.

      73, Barry
