This map of 6-July-2005 covers from 15:25z to 18:55z. DX everywhere along this day! At 15:30 a huge cloud above nortern France rises MUF over 144 MHz, 10 minutes later a second huge cloud appears above southern France. At 16:00 both clouds began to merge in a incredible one covering almost all the country. At 16:25 two new clouds appear above the Slovak Republic and western Bulgaria and at 16:50 another one at the south of Norway. At 17:10 two new clouds appear above Lithuania and Bulgaria and only 15 minutes later yet another one above nortwest Italy. Finally, at 17:45 a huge cloud formed abover northern Poland and lasting for about one hour. MUF was over 200 MHz several times and some QSO were made above 2500 Km.

Available maps this day::  |  09:45 - 13:07 15:25 - 18:55  |  19:55 - 20:52  |

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.

Ver? que algunas estaciones solo pasaban los cuatro primeros d?itos del locator, normalmente eran estaciones con las que ya hab? contactado repetidas veces con ellas anteriormente. El equipo usado fue un IC 706 Mk2 g y dos antenas yagi de 9 elementos, con amplificador de 2x 4cx250, trabajando a unos 200w de salida. Esto es todo de momento, saludos cordiales.

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)
