144 MHz in Europe - 2005

|  ES > 2800km  |  TR > 2800km  |  ES num. QSO/square |  ES clouds location  |

Known QSO over 2800 km via Sporadic-E

Known QSO over 2800 km via Tropo ducting

Number of QSO per square made via Sporadic-E
 

In this map you can see the locations more favoured by Sporadic-E propagation on 144 MHz. The coloured spot in each square shows the number of QSO reported by stations located in it. At a glance you can see that although some QSO has been made from almost any square in Europe, the more favored areas have been The Netherlands, Belgium, Bulgaria (as in 2004), and central Europe in general, while very few QSO have been made from northern/central France (as in 2004). It's also noticeable the unusual high number of QSO made from Finland.  This map has been made based of the 15049 QSO that are in my database, however you have to bear in mind that surely much more QSO have been made, so the map is just an approximate estimation that allows an overview of how the Sporadic-E season was, it's not 100% accurate.

Average location of Sporadic-E clouds

This map show an estimation of the location of the Sporadic-E reflection areas (clouds) that allowed the 15049 QSO that I have in the database. The coloured spots in each square show the number of QSO made when the reflection was calculated to be above that location. You can clearly see that the clouds mainly formed over eastern Poland and south-western France, there is gap over southern Germany and Czech republic. However you have to understand that this map is the result of calculations made from the reported contacts, so the lack of coloured spots over central IN field (for instance) does not mean that no ES clouds have formed over there, but simply that no QSO have been reported in this sense.
