This map from 2-May-2004 covers from 09:49z to 10:24z. Although at least two sporadic-E QSO were reported on 2m. between DL and LZ/YO I have my doubts about them being really sporadic-E, taking into account that there is no evidence of other QSO on the lower bands, as you can see in this evolution map. I would rather think about MS as the origin of the QSO.

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

It 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 QSOs 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 the lack of data mentioned above.
