This map of 5-July-2004 covers from 12:50z to 13:52z. This was a short but curious opening, with three separate reflection points almost at the same time. One over southern Portugal, another over the Balearic Isl. and another over central Spain. You can also look at the other map covering from 17:50 to 20:08z

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.

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)
