Abstract. An automated mapping technique for representing the hourly behaviour of the ionosphere was presented by Rush in 1976. The technique is based on updating the predicted monthly median maps of ionospheric pa- rameters with hourly observations. The procedure was accomplished by com- puting the differences between the predicted medians and the hourly values of ionospheric parameters that are observed at specific locations on the globe. This technique provides the basis for extending and extrapolating the influ- ence of an observation from the observing location to the region surrounding the observing location, this method is very complicated, so in our research we have used another newly developed method. Our programme suggests a new mapping technique method to draw the maps based on updating the monthly median of ionospheric parameters predicted with geographic coordinates.
