This map of 5-July-2004 covers from 17:50z to 20:08z. Once again several separate clouds at the same time. The first appears over south-east France (as so often this year) and a little later, at 18:50, a new cloud reaches a high foEs over the Atlantic allowing a good number of QSO between Azores Isl. and Portugal/Spain. You can also look at the other map covering from 12:50 to 13:52z 

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

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.

Logs received:

Sven, SM7NNJ has send us his complete 6m. log for years 2003 and 2004 in ADIF format.
Too long to be listed here, but very helpful for the calculations. Many thanks indeed Sven

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)
