Two maps are available for 6-June-2003, one covering the first opening from 08:40z to 10:14z (that first allowed QSOs from UR to YU and S5 and little later from UR/UA6 to F, DL, S5, YU, OE, OK and from SP to UR, UA6 and UA3) and the other from 15:00z to 17:26z  (that initially allowed QSOs from UA6 to UA1/UA3 and from UA4 to LY, then from UA4 to UB5/LZ and from LY to UN and finally from SP to UA4)

This animation can take some time (minutes) to load because of its size. Be patient and wait !
If you can see the map only partially press the "Refresh" button of your browser.

It 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 QSOs 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. and 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 the lack of data mentioned above.

Use the "Stop" button of your browser to stop the animation and the "Refresh" button to run it again from te begining.
