Oblique ionograms derived from the current vertical incidence ionogram measured by the Digisonde at Pruhonice (50.0 N, 14.6 E) on 2017-11-18 at 13:00 UTC.
The actual Operational MUF for the x mode wave for each radio path is indicated.
Es traces are not plotted for frequencies higher than 40 MHz. The highest Es MUFx values for 1 hop and 2 hop links for any of the 10 radio paths are shown in a table.
Note that all ionograms only apply to radio paths where Pruhonice is at the midpoint of the path.
For further information see the info page.
