This map of 8-July-2004 covers from 10:00z to 13:57z. This was a really long and strong opening, with MUF over 200 MHz for many times. First cloud forms over Hungary, quickly spreading around and becoming a huge and highly ionized cloud. At 11:30 MUF goes below 144 MHz for a while, but 20 minutes later it comes up again, this time over central Germany and a little later, at 12:00, also over Austria spreading then towards southern Germany. You can also look at the other map covering from 15:20 to 16:28z

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)
