This map of 2-July-2005 covers from 16:00z to 18:37z. Between 16:07 and 16:30 there was a very inconsistent opening due to a cloud above southern Sardinia Isl. One hour later, at 17:40 a QSO was reported beween EA4 and CT3, however I have my doubts it was really sporadic-E. Then, at 18:05 another cloud above central France rised FoES and provided a few more QSO in 144 MHz for about 20 minutes. (You can also watch the map covering from 08:15 to 10_32)

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)
