Estimated ES cloud 2-July-2004

This map of 2-July-2004 covers from 12:35z to 14:35z. First cloud formed at the west of Sardinia Isl. and first QSO on 2m was at 12:43h. A little latter (12:50) a new reflection area appears over south-east France (As so many times this year). At about 13:15 both clouds seem to join in a huge cloud that lasts till 14:00, when it moves towards central-northern France while foEs goes down. You can also look at the other map covering from 18:20 to 19:32z

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)
