This map of 19-May-2005 covers from 14:10z to 17:10z. The first signs of sporadic-E reaching 144 MHz were detected about 14:12z when EA7 was worked into G. A little later at 1430z a big "cloud" formed over northern EA allowing many QSO between southern EA/CT and EI, G, PA y ON. One hour later, at 15:30 that cloud began to vanish but right a the same moment two other clouds appeared, one over the mediterranean coast of France allowing QSO between southern EA and I/S5 and another at the south of Sweden allowing QSO between 9A/I and LA and from PA to OH. These two new clouds lasted, with some interruptions, till 17:00z.

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 and basically from DX-spots collected by DXMAPS. 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)
