This map of 24-June-2004 covers from 09:30z to 13:15z. As the day before, MUF was over 144 MHz at some part of Europe almost all day from 05:45 to 16:43 (11 hours!!). The fun begun early in the morning, when at 6:00 a cloud reached a high MUF over Moldovia, moving towards central Romania a little later (8:00). At 8:30 a new cloud appears over northern Italy and at 8:50 yet another one over North-East Belarus (At that time 3 different clouds where providing QSOs on 144 MHz at the same time!). At 9:15 a new reflection point appears over Croatia. At 10:40 a new cloud reaches 144 MHz over North-East Spain and at 11:00 another one over central Italy/Corsica. On the map you can clearly see that along the following hours the cloud over Spain moves Northwards and the cloud over Italy moves Westwards. Finally a new reflection point appears at 15:55 over southern Germany. The map was so large that I have had to cut it into three parts. You can also look at the other maps covering from 05:45 to 09:30z and from 13:15 to 16:43z
This animation can take some time (minutes) to load because
of its size. Be patient and wait !

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.
