This map of 25-June-2004 covers from 08:30z to 09:48z. This was another spotty opening due to an ES cloud rising the MUF up to 144 MHz over South-Eastern France, allowing a few QSO.  There was apparently another ES cloud allowing one or two QSO between England and Portugal, but the lack of reports on the lower bands (50 MHz) points to the possibility that these QSO were actually made via MS.

This animation can take some time (minutes) to load because of its size. Be patient and wait !

If you can see the map only partially press the "Refresh" button of your browser.

Use the "Stop" button of your browser to stop the animation and the "Refresh" button to run it again from te begining.

This map shows the evolution, size and MUF of the sporadic-E cloud that caused the opening on 144 MHz. and it is an estimation based on the information I have picked up here and there of QSO and reports of European stations. I don't claim it to be accurate but just an estimation that could help understand what happened that day.

Also please notice that sometimes you will see MUF rise very quickly.  This is because of the almost complete lack of data for frequencies between 51 and 144 MHz. that leads to shown MUF rising almost 90 MHz in one minute.  You should understand that this is not the usual behaviour of MUF, but the result of that lack of data.

You can help develop these maps!. After the openings, please send me your logs of 50, 70 and 144 MHz QSO via sporadic-E (Much preferably in ADIF format)
