For this years Perseids meteor shower antenna was turned to the west for Norwegians. While antenna was pointing to the west there were fewer pings than usual Perseids provides. But there are fever high power stations in the west than south. It was interesting to notice ping starting with Norwegian/Danish while it was turned to in English language at the end.

The shift from Norwegian to English stations can be explained with the level of ionization: once the meteor hits, the level of ions is very high, and a short skip with a sharp reflection angle is possible. When the ionization gradually fades, the last man standing will be signals with the most obtuse (blunt) angle..
Meteors can bring a MUF up to 500 MHz. (My personal record is tv channel E26/ 511 MHz). Which means a very sharp short skip on FM. (My shortness record is YLE Kerimäki at 308 km).
